ONE OF THE BEST BOOKS OF THE YEAR—NPR, Library Journal, Book Riot

Multiverse travel is finally possible, but there’s just one catch: No one can visit a world where their counterpart is still alive. Enter Cara, whose parallel selves happen to be exceptionally good at dying—from disease, turf wars, or vendettas they couldn’t outrun. Cara’s life has been cut short on 372 worlds in total.

On this dystopian Earth, however, Cara has survived. Identified as an outlier and therefore a perfect candidate for multiverse travel, Cara is plucked from the dirt of the wastelands. Now what once made her marginalized has finally become an unexpected source of power. She has a nice apartment on the lower levels of the wealthy and walled-off Wiley City. She works—and shamelessly flirts—with her enticing yet aloof handler, Dell, as the two women collect off-world data for the Eldridge Institute. She even occasionally leaves the city to visit her family in the wastes, though she struggles to feel at home in either place. So long as she can keep her head down and avoid trouble, Cara is on a sure path to citizenship and security.

But trouble finds Cara when one of her eight remaining doppelgängers dies under mysterious circumstances, plunging her into a new world with an old secret. What she discovers will connect her past and her future in ways she could have never imagined—and reveal her own role in a plot that endangers not just her world but the entire multiverse.

“Clever characters, surprise twists, plenty of action, and a plot that highlights social and racial inequities in astute prose.”—Library Journal (starred review)

A searing sci-fi thriller about a woman reckoning with her past to solve a series of sudden and inexplicable deaths in the face of a coming apocalypse—from the Compton Crook Award–winning author of The Space Between Worlds.

“A bold, beautiful, gut-punch of a story, at turns ferocious and poetic—and sometimes both at once.”—Veronica Roth, New York Times bestselling author of Chosen Ones

“[Those Beyond the Wall] reads like Mad Max: Fury Road was written by Phillip K. Dick and N.K. Jemisin.”—CrimeReads


In Ashtown, a rough-and-tumble desert community, the Emperor rules with poisoned claws and an iron fist. He can’t show any sign of weakness, as the neighboring Wiley City has spent lifetimes beating down the people of Ashtown and would love nothing more than its downfall. There’s only one person in the desert the Emperor can fully trust—and her name is Scales.

Scales is the best at what she does: keeping everyone and everything in line. As a skilled mechanic—and an even more skilled fighter, when she needs to be—Scales is a respected member of the Emperor’s crew, who’s able to keep things running smoothly. But the fragile peace Scales helps to maintain is fractured when a woman is mangled and killed before her eyes. Even more incomprehensible: There doesn’t seem to be a murderer.

When more bodies start to turn up, both in Ashtown and in the wealthier, walled-off Wiley City, Scales is tasked with finding the cause—and putting an end to it by any means necessary. To protect the people she loves, she teams up with a frustratingly by-the-books partner from Ashtown and a brusque-but-brilliant scientist from the City, delving into both worlds to track down an invisible killer. 

But the answers Scales finds are bigger than she ever could have imagined, leading her into the brutal heart beneath Wiley City’s pristine façade and dredging up secrets from her own past that she would rather keep hidden. If she wants to save the world from the earth-shattering truths she uncovers, she can no longer remain silent—even if speaking up costs her everything.
