Submersed

Praise

“Deft. . . . Captivating. . . . Page-turning. . . . Frank has an eye for the unique. . . . He works hard for his readers . . . immersing them in awe-inspiring levels of context and detail.”
—Dave Shiflett, The Wall Street Journal

“If the title alone doesn’t have you jamming the preorder button, the titillating story of what drives people to sink to the depths in amateur submarines will.”
—Lizz Schumer, People, “People Picks the Best Nonfiction Books of Summer 2025”

“A strange and beautiful journey into the depths—literally—of obsession and intrigue at the edge of the known world.”
—Jonathan Meiburg, author of A Most Remarkable Creature

“For as long as I can remember, I’ve been afraid of the ocean. So begins Matthew Gavin Frank’s thrilling study of an obsession—to sink below the surface, to depths both metaphoric and in fact. Frank travels the world, combs through archives, gathers stories of a world most of us will never witness, even as it is all around us. Full of wild characters and strange histories, by the end we are convinced, in no small part by the beauty of his language, that this is one of the most important stories ever told.”
—Nick Flynn, author of This Is the Night Our House Will Catch Fire

“Submersed might be the scariest book I’ve ever read: I can feel little bubbles of panic float up in me if I just imagine stepping onto an amateur submarine. But I’ll follow an essayist like Matthew Gavin Frank anywhere, and he’s crafted an exceptional journey into the down deep, beautifully examining ‘the nagging drive to embed the body into a balloon-like enclosure and float alongside the fishes.’ Reading this book, I felt rearranged at an atomic level. What a gift.”
—Kristen Radtke, author of Seek You: A Journey Through American Loneliness

“Submersed is a dizzying and riveting descent into obsession, toxic masculinity, and the irresistible desire to reach new depths or tell a good story. Matthew Gavin Frank plunges far beneath the surface to observe the best and worst of humanity. A work of narrative nonfiction that is as astonishing as diaphanous sea creatures. One of the best books I’ve ever read.”
—Michele Filgate, editor of What My Father and I Don’t Talk About

“Matthew Gavin Frank is a master storyteller. A poetic true-crime cousin of Truman Capote’s classic In Cold Blood, Submersed navigates the horrific murder of journalist Kim Wall, the eccentric culture of the DIY submersible community, and our human relationship to large bodies of water. Believe me, you won’t be able to put this book down until you arrive at the very last page. It’s stunning, commanding, and haunting all at once.”
—S. Kirk Walsh, nationally bestselling author of The Elephant of Belfast

“From the DIY pop-up postindustrial steampunk shipyards of Denmark to misogyny and murder, Matthew Gavin Frank is a furnace of intelligence and curiosity. Plumbing the depths and heights of the sea and the human condition, Submersed is an environmental story about obsession and desire, including Frank’s own, where he becomes embedded in the oceanic kelp of cultural complexities and complicated lives. Radiant, dark, elegant, perceptive, Submersed reveals how external landscapes affect our internal ones.”
—Kerri Arsenault, author of Mill Town

“Scintillating. . . . Frank’s thoughtful approach resists the temptation to revel in lurid details. Instead, he delves into the intriguing history of submarines and how the lack of personal submersible regulation results in catastrophes like the implosion of the Titan submersible. . . . Excellent for book groups, Frank’s unique approach is a distinguished tour de force.”
—Colleen Mondor, Booklist (starred review)

“A well-documented look at the submarine community that combines true crime with science writing and history. It’s a good pick for fans of Erik Larsen, as Frank also intersperses the events of a crime within a subject’s larger context, all in engaging and haunting writing.”
—Maria Ashton-Stebbings, Library Journal

“A sharp researcher and stylish writer who’s ‘obsessed with obsessives,’ Frank sets aside his lifelong fear of the ocean in this excellent book to plumb the peculiar depths of the DIY sub community. . . . Frank is witty and incisive . . . and he draws wonderful connections throughout. . . . A fascinating voyage among the hidden tides shaping a social niche.”
—Kirkus Reviews

“[Frank’s] years of research and reporting are distilled into engaging anecdotes that have the flow of lyrical prose.”
—Anna Ridilla, Gasparilla Magazine

“[An] aquatic escape. . . . Frank is afraid of the ocean, but that doesn’t stop him from diving into the water to learn about the murky world of DIY submarines.”
—John McMurtrie, Kirkus Reviews, “4 Nonfiction Books to Transport You This Summer”
