Book cover of The Worst Ship in the Fleet

Danny Anthony Bonsangue Author Of Entanglement

From my list on unlikely heroes facing existential threats.

Why am I passionate about this?

I have loved science since I was young. I was obsessed with watching videos and reading books by scientists like Michio Kaku and Neil DeGrasse Tyson, where they explored concepts like time travel, black holes, and the quantum realm. In college, I majored in environmental studies, mostly because of my love for both natural science and policy. In addition to basic biology and ecology, I learned about what is hurting the Earth and the consequences of not acting fast. I contributed to a white paper on “Ecocide,” or deliberate destruction of the natural environment, by the Russians in Ukraine. I also contributed to the Journal of Science and Technology Law.

Danny's book list on unlikely heroes facing existential threats

Danny Anthony Bonsangue Why did Danny love this book?

I love this book because it is a story about space travel, and it features a flawed character as the protagonist. Most people are flawed; it’s very hard to find a morally perfect person, so I appreciate a book that features an imperfect protagonist.

I am also a fan of redemption—one of my books features a character who has done terrible things but can redeem himself with one good thing.

Danny's book list on unlikely heroes facing existential threats

Danny Anthony Bonsangue Why did Danny love this book?

I love this book because it shows that, even in the face of existential demise, humans cannot set aside their differences so easily.

You’d think that, with a comet headed toward Earth causing certain destruction, interpersonal conflicts would take a backseat. But humans are still humans—we still always want to think we’re right, we still have pride, and we still have interests that, although similar to one another, are not exactly the same. It’s self-published, like my own.

What is this book about?

1908... Siberia... A tiny comet rips through Earth's atmosphere and explodes above the Tunguska region of Siberia, instantly engulfing thousands of square acres of the mostly desolate region. The explosion is heard for hundreds of miles, the light of the comet seen halfway across the globe. Had the comet hit a few hours earlier in a more populated area, millions would have been killed...

A century later, another comet - this one hundreds of times bigger and more powerful - encounters a black hole in deep space and is pushed onto a new, deadly course leading straight to Earth...

Danny Anthony Bonsangue Why did Danny love this book?

I love this book because it has a strong female lead character. These are rare in entertainment in general, and especially in sci-fi books, besides a few notable exceptions. It’s one of the reasons I decided to feature a woman as the protagonist in my book.

The novel also features a plot about humans living throughout space and how dangerous space might become when that happens. Like my own, it was self-published.

I love this book because not only is it a sci-fi novel, but it loops in a crime angle. Crime is my other favorite genre to read.

As a lawyer, I’ve always found ways to weave crime and the law into my novels. It also deals with humans living in other places than Earth, a concept I’ve always been interested in reading and writing about.

Book cover of Eyes in the Dust

Kev Harrison Author Of Below

From my list on subterranean horrors to make you avoid your basement.

Why am I passionate about this?

At university, I studied Classical Studies, which leans heavily into archaeology. As I went on more site visits, I became much more aware of the worlds and lives which exist below our feet. Later, when working as a teacher in Poland, I had the chance to visit one of Europe’s deepest active coal mines. The experience surprised me in so many ways, not least the oppressive heat and the darkness—something you feel you can almost touch. From that moment onward—especially as a horror writer—I’ve found myself wondering about the nightmares lurking below our world, as well as above, and beyond.

Kev's book list on subterranean horrors to make you avoid your basement

Kev Harrison Why did Kev love this book?

Like with Tim Curran’s The Underdewlling, above, Eyes in the Dust leans into the cosmic with its approach to what’s below our feet.

A giant borehole has been dug in an unnamed, developing world country revealing an inexplicable anomaly. Our story, though, focuses on a single individual’s perspective. Cortland—the archetypal faceless manager—comes face to face with the nihilistic reality of what lurks miles beneath the soil, and the horror is almost too much to bear.

What is this book about?

a DUNHAMS MANOR PRESS EXCLUSIVE from the author of THE SPECTACLE OF THE VOID. The world has moved on and left Cortland behind. His career as an academic has fizzled out, his fiancé is dead, and he remains haunted by the notion that it’s his fault. When a consulting firm contacts him with the opportunity of a lifetime—two months off the grid studying slime molds at the bottom of an ancient impact crater—he has no choice but to accept. He soon learns, however, that the crater holds dark secrets, that death itself is not an exit, but rather a welcoming…


Book cover of A Geologist Speculates

Frederick Lin Sutherland Author Of The Volcanic Earth: Volcanoes and Plate Tectonics : Past, Present & Future

From my list on the glories of global geology.

Why am I passionate about this?

My final high school year in Tasmania added a new topic, geology. I and my school friends knew little about it but signed up. In the first lesson, the teacher pointed at the adjacent sunlit river gorge saying “There is your laboratory.” We were hooked and most of us became professional geologists. I started off in museums where mineral, rock, and fossil collections were a font of knowledge and generated field collecting, research, and educational activities. This led to MSc and PhD degrees from universities at both ends of Australia. A base at the Australian Museum led to travel around Australia and visits to many overseas institutions and meetings.

Frederick's book list on the glories of global geology

Frederick Lin Sutherland Why did Frederick love this book?

Here, a seasoned geologist gathers several themes of his research interests, poses critical questions on apparent anomalies within them, and considers their resolution. He does this by giving free rein to informed lateral thinking on these topics. This produces an unusual book in the annals of geological writing, presenting thought-provoking and rewarding reading.

The thematic chapters are written in a fluent expression of the concepts involved, reinforced through a range of illustrative means. There are superb photographs of gems, minerals, and rocks as specimens and rocky exposures from many sources. Geological diagrams underpin explanations, superimposed maps highlight large-scale geological structures, and even images of paintings, historical scenes, postcards, and stamps reinforce particular points. The closing sections enter the realms of life on Earth, seen as coordinated biological and geological evolution.

Book cover of A Street Dog Named Pup

Linda Newbery Author Of This Book Is Cruelty Free: Animals and Us

From my list on animals and us.

Why am I passionate about this?

I'm mainly known as an author of fiction for young readers, but animal awareness is an important part of my life and I decided to write about it.  I’ve been vegetarian for many years, and vegan for the last four: I decided long ago that no animal was going to die so that I could eat it. From early childhood, I loved animal stories, and as I grew older it baffled me that we care for our pets while thinking of other creatures as food. I spend a lot of my time campaigning for animals – for better treatment of farm animals, against bloodsports like fox-hunting and shooting, and for better awareness of the natural world and how we must look after it.

Linda Newbery Why did Linda love this book?

Many people, including me, are describing this as a modern classic, a Black Beauty for dogs, and for our age. When he’s cruelly dumped on a London street and left to fend for himself, Pup, a German Shepherd cross, teams up with other homeless dogs and learns survival skills, confronting many dangers. Through the various dogs in this group and their stories, Gill Lewis raises various issues about dog-owning and breeding: abandonment, puppy-farming, and the deliberate selective breeding of flat-faced dogs that leads to breathing problems. Pup even gets reluctantly involved in the horrors of organised dog-fighting. It’s practically guaranteed to keep you hooked.

Book cover of The Ice Limit

Peter Hogenkamp Author Of The Woman From Death Row

From my list on thrillers you probably haven't heard about.

Why am I passionate about this?

I love thrillers that give you something to think about, keep you on the edge of your seat and take you to new places. And, although I also like Daniel Silva and Lee Child and Tess Gerritsen et al, I love to find new voices in the thriller genre, especially ones (like mine) that haven’t become household names. And I am especially drawn to thrillers with great prose and great characters. Try some of the books I recommended. You will not be sorry.

Peter Hogenkamp Why did Peter love this book?

It’s possible that you have heard of Preston & Child—in fact, you should have. Their Agent Pendergast thriller series is incredible. And, although this is a stand-alone book that isn’t part of the Pendergast series, it has all the signature elements of the dynamic duo: great writing, fascinating science, and unforgettable characters.

Throw in just a hint of sci-fi and an exotic location into the mix, and you have the perfect thriller. And I bet you will love it.

In the desolate reaches of southernmost Chile, a remarkable discovery has been made. It is a massive meteorite whose very existence will change science-and perhaps even mankind. In great secrecy, an expedition sets out on a converted tanker, bound for the bottom of the world. But almost as soon as the recovery process begins, the mysteries and enigmas begin to mount. What appeared to be simply an engineering challenge quickly becomes a perilous undertaking, for the bizarre, implacable artifact may not be what it seems. And when a raging storm drives the tanker beyond the dangerous Antarctic latitude known as…


Book cover of The Day of the Triffids

James Marshall Author Of The Poster

From my list on dystopian books set in Britain.

Why am I passionate about this?

I’ve loved reading alternative visions of Britain since I read a Strontium Dog saga in ‘2000AD’ as a boy. What was science fiction then has become closer to reality now. The idea of one event, such as a meteor shower in Triffids or a virus in ‘Grass,’ causing havoc worldwide is gripping. I prefer the British stories because they are closer to home. Many of these were written close to the Second World War, and their authors describe deprivation in unflinching detail. Recent political events have turned my mind to how human actions can cause dystopian futures, as in Orwell’s 1984.

James' book list on dystopian books set in Britain

James Marshall Why did James love this book?

Like H.G. Wells, Wyndham is excellent at depicting normal people who are dealing with an unusual event in normal locations. This creates a level of reality that makes the circumstances more horrific. I could imagine myself in those places, with those people.

The Triffids have never translated well to the screen because the plants look awkward. This isn’t the case in the book. This is my favorite of all the Wyndham books because of their journeys and their descriptions of the landscape around them.

What is this book about?

When Bill Masen wakes up in his hospital bed, he has reason to be grateful for the bandages that covered his eyes the night before. For he finds a population rendered blind and helpless by the spectacular meteor shower that filled the night sky, the evening before. But his relief is short-lived as he realises that a newly-blinded population is now at the mercy of the Triffids.

Once, the Triffids were farmed for their oil, their uncanny ability to move and their carnivorous habits well controlled by their human keepers. But now, with humans so vulnerable, they are a potent…


Book cover of Down to Earth

Sarah Marie Jette Author Of What the Wind Can Tell You

From my list on for siblings and scientists.

Why am I passionate about this?

I’ve been an elementary school teacher for 14 years. In that time, I’ve read a lot of children’s books. In my classroom, science is one of my students’ favorite subjects. Though they love fantasy and magic, they are inspired by the power of science. Each of the books I’ve recommended is part of my classroom library, is used in a read-aloud or as a mentor text in writing lessons. My students connect with the characters and experience the marvels of science along with them. These books are some of their favorites.

Betty Culley writes the most beautiful books. Down to Earth is about a boy named Henry who watches a meteor fall from the sky. It crashes onto the land owned by his family and causes some magical changes in his community. Some people fear it, others want to use the meteor for profit. As I read the book, I learned so much about meteors and nature, but also about love, family, and friendship.

Henry has always been fascinated by rocks. As a homeschooler, he pours through the R volume of the encyclopedia (to help him identify the rocks he finds). So, when a meteorite falls in his family's field, who better to investigate than this rock enthusiast--with his best friend, James, and his little sister, Birdie, in tow, of course.

But soon after the meteorite's arrival, the water in Henry's small Maine town starts drying…
