Mr. Penumbra's 24-Hour Bookstore

A Winner of the Alex Award, a finalist for the Los Angeles Times Book Prize for First Fiction, named a Best Book of the Year by NPR, Los Angeles Times, and San Francisco Chronicle

The Great Recession has shuffled Clay Jannon away from life as a San Francisco web-design drone and into the aisles of Mr. Penumbra's 24-Hour Bookstore. But after a few days on the job, Clay discovers that the store is more curious than either its name or its gnomic owner might suggest. The customers are few, and they never seem to buy anything — instead, they “check out” large, obscure volumes from strange corners of the store. Suspicious, Clay engineers an analysis of the clienteles behavior, seeking help from his variously talented friends. But when they bring their findings to Mr. Penumbra, they discover the bookstores secrets extend far beyond its walls. Rendered with irresistible brio and dazzling intelligence, Robin Sloan's Mr. Penumbra's 24-Hour Bookstore is exactly what it sounds like: an establishment you have to enter and will never want to leave.

“A real tour de force [and] a beautiful fable....The reader is swept along by Sloan's enthusiasm.” George Saunders, BLIP Magazine

“Part love letter to books, part technological meditation, part thrilling adventure, part requiem....Eminently enjoyable, full of warmth and intelligence.” The New York Times Book Review

“One of the most thoughtful and fun reading experiences you're likely to have this year....There's so much largehearted magic in this book.” NPR

“A jaunty, surprisingly old-fashioned fantasy about the places where old and new ways of accessing knowledge meet...[Mr. Penumbra's 24-Hour Bookstore] cleverly uses the technological age in the service of its fantasy....Sloan's ultimate answer to the mystery of what keeps people solving Penumbra's puzzle is worth turning pages to find out.” Tess Taylor, San Francisco Chronicle

“[A] winning literary adventure....Sloan grounds his jigsawlike plot with Big Ideas about the quest for permanence in the digital age.” Thom Geier, Entertainment Weekly

“Fantastic....I loved diving into the world that Sloan created, both the high-tech fantasyland of Google and the ancient analog society. It's packed full of geeky allusions and wonderful characters, and is a celebration of books, whether they're made of dead trees or digits.” Jonathan H. Liu, Wired, GeekDad

“What makes Mr. Penumbra's 24-Hour Bookstore so impressive is Sloan's great gift for storytelling and his cast of brilliant, eccentric characters.

“Beguiling....The plot is as tight as nesting boxes, or whatever their digital equivalent....Sly and infectious.” Karen R. Long, The Cleveland Plain Dealer
