Book cover of A Portrait of the Artist as a Young Man

Mark Rennella Why did I love this book?

Joyce’s novel is the first of four literary works that helped me to envision myself as a writer. I read it in 11th grade.

The opening of the novel startles the reader because it uses language to depict the point of view of a baby’s first conscious thoughts, listening to a parent calling him by a nickname:

Once upon a time and a very good time it was there was a moocow coming down along the road and this moocow that was coming down along the road met a nicens little boy named baby tuckoo. His father told him that story: his father looked at him through a glass: he had a hairy face. He was baby tuckoo.

Joyce showed me that a written description like this wasn’t just trying to be a mirror of the world. A style of writing could also convey meaning and feeling. That was a revelation.

What is this book about?

A masterpiece of modern fiction, James Joyce's semiautobiographical first novel follows Stephen Dedalus, a sensitive and creative youth who rebels against his family, his education, and his country by committing himself to the artist's life.

"I will not serve," vows Dedalus, "that in which I no longer believe...and I will try to express myself in some mode of life or art as freely as I can." Likening himself to God, Dedalus notes that the artist "remains within or behind or beyond or above his handiwork, invisible, refined out of existence, indifferent, paring his fingernails." Joyce's rendering of the impressions of…


Book cover of The Collected Poems of Emily Dickinson

Mark Rennella Why did I love this book?

I read Dickinson in high school and college. Her poetry impressed me with its unique ability to create powerful images and ideas with just a few words:

Our lives are Swiss—
So still—so Cool—
Till some odd afternoon
The Alps neglect their Curtains
And we look farther on!

Her power of imagination was astounding. For somebody who had lived most of her life in a very circumscribed context of the city limits of Amherst, Massachusetts, her poetry was expansive. She achieved amazing heights of artistry even though she was barely recognized during her time. Her poems are a monument to her belief in herself, which is the foundation of creating a compelling and persuasive voice in writing.

What is this book about?

Emily Dickinson (1830-1886), the reclusive and intensely private poet saw only a few of her poems (she wrote well over a thousand) published during her life. After discovering a trove of manuscripts left in a wooden box, Dickinson’s sister Lavinia, fortunately, chose to disobey Emily’s wishes for her work to be burned after death. With the help of Amherst professors, Lavinia brought her sister’s gifted verse into print. “The Collected Poems of Emily Dickinson” brings together the first three series of her posthumous publications which debuted respectively in 1890, 1891, and 1896. It is here in this collection that we…


Book cover of Narrative of the Life of Frederick Douglass, an American Slave

Mark Rennella Why did I love this book?

While writing a paper about Douglass in graduate school in the 1990s, I learned that he had to overcome two obstacles to establishing an authentic voice in his own book.

First, abolitionists argued against slavery by claiming it dehumanized the slave. While that could be true, this theory could not account for charismatic Black writers like Douglass who were anything but dehumanized. Second, slave narratives in the antebellum era often followed a certain formula that limited the narrator’s originality.

In one striking passage in the Narrative, Douglass overcomes both restrictions by evoking an image of his body that offers visual testimony to creatively push back on these limiting conventions: “My feet have been so cracked with the frost [felt during cold nights during enslavement], that the pen with which I am writing might be laid in the gashes.”

What is this book about?

Packaged in handsome and affordable trade editions, Clydesdale Classics is a new series of essential literary works. From the musings of literary geniuses like Mark Twain in The Adventures of Huckleberry Finn to the striking personal narrative of Harriet Jacobs in Incidents in the Life of a Slave Girl, this new series is a comprehensive collection of our literary history through the words of the exceptional few.

The Narrative of the Life of Frederick Douglass is perhaps the most widely read and well-known slave narrative. Originally published in 1845, the work was an instant success, selling more than 11,000 copies…


Book cover of The Prelude

Mark Rennella Why did I love this book?

This long poem depicts the “prelude” – the influences from childhood – of William Wordsworth’s life as a poet. In other words, this literary biography explores the source of this poet’s unique voice. This poem was another exciting discovery made during my years as a graduate student.

There are many written works that explore the influence of a writer’s early life on the development of their unique poetic vision. A more recent example is a favorite of mine, Gabriel Garcia Marquez’s Living to Tell the Tale.

But, for me, Wordsworth stands out because of the incredible sustained poetic voice, vision, and rhythm of this piece, which he worked on and revised over his lifetime. I think the Two-Part Prelude of 1799 is better than the longer version of 1850. The Prelude of 1799 is long enough to take the reader to a new world, but short enough so the magic atmosphere evoked by the writing can be maintained through one sitting.

1 author picked The Prelude as one of their favorite books, and they share why you should read it.

What is this book about?

"The Prelude" is William Wordsworth's epic reflection on his lifetime journey as an artist and is widely considered to be one of his most significant works. First published in 1850 after the poet's death, Wordsworth began working on the blank verse poem in 1798 and continued modifying and expanding it for the rest of his life. Two earlier versions of the poem have been found and published, showing the evolution of this monumental work. A first version, called the "1799 Prelude", is the poem in its earliest and shortest stage. A second version, the "1805 Prelude", is much longer and…


Book cover of The Craft of Revision

Mark Rennella Why did I love this book?

This writing instruction book came to my aid as I began to teach writing at Harvard University in the late 1990s, when I was trying to help college students cultivate their own voice as writers.

The title was brilliant, surprising the reader that the subject was revision and not writing, per se. This focused on a fundamental truth, which is that good writing – whether it be fiction or non-fiction, artistic or professional – almost always goes through several revisions. Students often recoil at the idea of revisions because they threaten to burden them with more work.

What Murray underlined (and a point I’ve reiterated) is that revisions provide the opportunity to improve your work. The more that writers are comfortable with making revisions, the easier it will be to cultivate and improve their voices in their written work.

The One-Idea Rule: An Efficient Way to Improve Your Writing at School and Work

By Mark Rennella,

Book cover of The One-Idea Rule: An Efficient Way to Improve Your Writing at School and Work

What is my book about?

The One-Idea Rule is an answer to a question I posed to myself as a humanities instructor: “What is the best piece of writing advice I can share with students?” In the beginning of my teaching career in the 1980s, I hadn’t encountered a writing methodology that tended to the most prevalent problem I witnessed: a lack of focus. I devised the “one-idea rule” to fill that deficiency. The rule simply states that every component of a well-written document should express only one idea.

Readers respond very positively to focused arguments. We read to learn new things, but it’s hard to learn too many things at once. When writers truly understand this aspect of the one-idea rule, they can return to the rule with confidence to sustain and cultivate their own unique voices.

New book alert!

Why am I passionate about this?

I come by my interest in history and the years before, during, and after the Second World War honestly. For one thing, both my father and my father-in-law served as pilots in the war, my father a P-38 pilot in North Africa and my father-in-law a B-17 bomber pilot in England. Their histories connect me with a period I think we can still almost reach with our fingertips and one that has had a momentous impact on our lives today. I have taken that interest and passion to discover and write true life stories of the war—focusing on the untold and unheard stories often of the “Average Joe.”

What is my book about?

October 24, 1944, is not a day of national remembrance. Yet, more Americans serving in World War II perished on that day than on any other single day of the war.

The narrative of No Average Day proceeds hour by hour and incident by incident while focusing its attention on ordinary individuals—clerks, radio operators, cooks, sailors, machinist mates, riflemen, and pilots and their air crews. All were men who chose to serve their country and soon found themselves in a terrifying and otherworldly place.

In its telling of the events of October 24, No Average Day proceeds hour by hour and incident by incident. The book begins with Army Private First-Class Paul Miller's pre-dawn demise in the Sendai #6B Japanese prisoner of war camp. It concludes with the death…
