The most recommended books about galactic empires

I have enjoyed literally hundreds of hours of thrilling military SF in the series of which this book is the first novel. David Weber is one of two authors who have invented new SF sub-genres. In David’s case, the sub-genre is often called space opera. The other author is David Drake. His Hammer’s Slammers stories are now considered the first books in the ‘space marines’ sub-genre.

David Weber’s story universe is huge. I sometimes think it’s too big in the sense that he tries to weave too many sub-plots into the larger story arc. But his first book is quite moderate in this regard. I started writing my own military SF novels partly because Weber wasn’t writing new sequels fast enough to satisfy my thirst for thrilling space combat.

By now, it should be clear I like trilogies, reading and writing them. The Lyhhrt Trilogy is a perfect example of incredible imagination and wordsmith talent. As in some of my writings, there is palpable lyrical style and a dense compositional approach to a story that explores the awful and worming guts that must be, de facto, the only way any vast empire can form, emboweled and ejected into reality. The Galactic Federation here is a hostage of the nobility or despicable evilness of those carrying authority in the governing organization: game of thrones anyone? The spine of the story, as in The Law, is of a GalFed Judge who realizes cruelty and slavery are the crude reality in an empire focused on satisfying the same base urges that humanity spends so much energy on today. A well envisioned complicated and messy universe, the way it should be.

The War World series of novels, novellas, and short stories drew me in because they represent a microcosm of what happens when a civilization crashes in an inhospitable environment. I’ve been an avid fan of Jerry Pournelle’s CoDominium universe ever since reading West of Honor and seeing how it evolved for good and for bad through the War World lens, as developed by a long list of fantastic authors, kept intriguing me for years. Many of the concepts developed throughout the series had a marked influence on my own worldbuilding, and for that, it will always have a special place in my pantheon of books.

This series, to my mind, epitomizes the idea of a gradual rebirth after a galactic civilization collapses, leaving humans stranded on countless worlds with varying degrees of technology. I found the way in which Drake approaches said rebirth incredibly fascinating as well as entertaining, by using sentient artifacts of the long-vanished empire to guide humans back to the stars. And, as a dog lover, I really enjoyed him using oversized canines instead of horses for his pre-industrial cavalry.

I'd never known anything about Gypsy culture (except cinematic stereotypes) until I read Silverberg's Star of Gypsies. Even though this book takes place on other worlds, centuries into the future, the traditions and the society of Gypsies survives. These nomadic spacefarers have evolved into important pieces of a galactic empire – an empire upon which the protagonist will have a profound effect. I loved the inventive world building and the complex yet often humorous main character, Yakoub. The tale fully engaged me from the very beginning and is one of those books I give my highest compliment – a page-turner you don't want to put down.

First, this is in most respects the beginning (in internal chronology) of a wonderful SF series, the Vorkosigan Saga. Each book can be read in isolation but adds to the depth and richness of the series as a whole.

Second, the reader is introduced to Cordelia Naismith and Aral Vorkosigan, two strong and unique characters who meet under daunting circumstances that become even more challenging. The title aptly (if cryptically) describes the crisis with which Aral must cope, with a competence that conceals its almost unbearable effect on him.

Speaking of competence, it’s remarkable how Bujold conveys so much of the essence of two very different societies so efficiently.

I won’t lie; this series hurt my brain. It did not hold back with the twists or the depth of dialogue and intrigue either. I love it for the way it showed me the sheer complexity a series could offer. Asimov built a world that felt so real—complete with deep political intrigue, technological advancements, and power struggles that echoed across generations.

What captivated me most was how the storylines tied together over time, often referring back to events from the first book in ways that made everything feel interconnected. You don’t just read the Foundation series; you invest in it, piecing together the layers of Asimov’s universe as you go.

The story is full of big ideas—focusing not just on individuals but on the grand sweep of civilizations rising and falling. I felt that this series taught me the importance of understanding the long game: that things unfolding today may… show more.

Shards of Honor and Barrayar form a duology within the wider Vorkosigan Saga, and starting with them both is the best way to become acquainted with the wider series universe and with the origins of Miles Vorkosigan. All of the later books refer back to events that happen in Barrayar, and one of the core conflicts of the novel is the struggle between the conservative isolationists who don’t want to integrate with the rest of the galaxy, and the liberal reformists who do. The political intrigue is extremely well done, and the adventure is superb.

It's difficult to discuss what might make Baru unlikable without delving into spoilers, but that's fine because you must see this book through to appreciate it fully.

Baru, an accountant, finds herself caught in the jaws of empire when her homeland is colonized and one of her fathers is killed. Cold and calculating, Baru desperately claws her way to power in an attempt to fight empire from within, and along the way, must reckon with how much of herself she is willing to sacrifice for her goals. I can’t emphasize how bleak this book is, and part of that comes from watching Baru eat herself alive and be awful to other people.
