[STARRED REVIEW] Tidhar’s slippery metafictional tale lyrically entangles scientific fact, mysticism, and mental illness. This is a knockout

—Publishers Weekly

Brilliant and bizarre, Lavie Tidhar’s THE CIRCUMFERENCE OF THE WORLD is many things—but fundamentally it is a love letter to the Golden Age of science fiction, whether or not it deserves it (it does), as well as a love letter to its writers, whether or not they deserve it.

—Molly Tanzer, author of Vermilion and Creatures of Will and Temper

Caught between realities, a mathematician, a book dealer, and a mobster desperately seek a notorious book that disappears upon being read. Only the author, a rakish sci-fi writer, knows whether his popular novel is truthful or a hoax. In a story that is cosmic, inventive, and sly, multi-award-winning author Lavie Tidhar (Central Station) travels from the emergence of life to the very ends of the universe.

[STARRED REVIEW] Black holes, new religions, and powerful stories ensnare orbiting beings with their intrigue and potentiality in Lavie Tidhar’s science fiction marvel THE CIRCUMFERENCE OF THE WORLD…. Inquisitive, daring, and rich with possibilities, THE CIRCUMFERENCE OF THE WORLD is a speculative masterpiece.

—Foreword

Delia Welegtabit discovered two things during her childhood on a South Pacific island: her love for mathematics and a novel that isn’t supposed to exist. But the elusive book proves unexpectedly dangerous. Oskar Lens, a science fiction-obsessed mobster in the midst of an existential crisis, will stop at nothing to find the novel. After Delia’s husband Levi goes missing, she seeks help from Daniel Chase, a young, face-blind book dealer.

The infamous novel Lode Stars was written by the infamous Eugene Charles Hartley: legendary pulp science-fiction writer and founder of the Church of the All-Seeing Eyes. In Hartley’s novel, a doppelganger of Delia searches for her missing father in a strange star system. But is any of Lode Stars real? Was Hartley a cynical conman on a quest for wealth and immortality, creating a religion he did not believe in? Or was he a visionary who truly discovered the secrets of the universe?

Tidhar wins it all with this magnificently original mind-bender of a novel about a missing husband and a mysterious book that disappears as soon as you read it. THE CIRCUMFERENCE OF THE WORLD is two parts Philip K. Dick, two parts Brothers Strugatsky, and six parts blow your f**king mind.
