THE CIRCUMFERENCE OF THE WORLD

When a mathematician goes missing while searching for a legendary science-fiction novel, his wife hires a disabled book dealer to bring him home.

Maybe the universe’s energy really does get recycled, because this eclectic speculative novel manages to be simultaneously contemporary, nostalgic, and retro in a way that wouldn’t be unfamiliar to the SF icons to which it pays tribute. It’s a whodunit in structure but steeped in heavy philosophy with a few Beat flourishes to boot. Delia Welegtabit grew up on a remote island where her proximity to the stars gifted her with a love of mathematics. In London circa 2001, Delia is married to Levi Armstrong, another young mathematician who dreams of making sense of the universe. After Levi disappears in search of a long-lost copy of an obscure 1962 SF novel called Lode Stars by Eugene Charles Hartley, Delia hires Daniel Chase, whose prodigious literary knowledge is blunted by his prosopagnosia (face-blindness), to find him. Immediately, Daniel is summoned by Oskar Lens, a shadowy underworld figure whose delusions and paranoia make him a very dangerous adversary indeed. Stylistically, we’re deep into Jonathan Lethem territory (Chandler-esque detective story with a heavy dose of weird) before Tidhar pulls back the curtain on the wizard himself, Hartley, whose book speculates that we’re all sentient memories swirling inside a black hole. Menace endures, as predatory parasites dubbed “eaters” prey on these sentient memories unless one possesses a coded copy of Lode Stars, which protects its charge. In a familiar turn, Robert Heinlein drunkenly suggests to Hartley that if he wants to make millions, he should really start his own religion, which inspires the author to found the Scientology-esque Church of the All-Seeing Eyes before disappearing himself. The plot may collapse into noodle-bending nonsense, but Tidhar’s rich portrayal of the pulpy golden age of science fiction, distinctive characters, and nimble turns of phrase make for a cool confection.

A nifty artifact about the perils and prognostications of the science fictional world.
