This Is How You Lose the Time War

ONE OF NPR’S BEST BOOKS OF 2019

Two time-traveling agents from warring futures, working their way through the past, begin to exchange letters—and fall in love in this thrilling and romantic book from award-winning authors Amal El-Mohtar and Max Gladstone.

In the ashes of a dying world, Red finds a letter marked “Burn before reading. Signed, Blue.”

So begins an unlikely correspondence between two rival agents in a war that stretches through the vast reaches of time and space.
Red belongs to the Agency, a post-singularity technotopia. Blue belongs to Garden, a single vast consciousness embedded in all organic matter. Their pasts are bloody and their futures mutually exclusive. They have nothing in common—save that they’re the best, and they’re alone.

Now what began as a battlefield boast grows into a dangerous game, one both Red and Blue are determined to win. Because winning’s what you do in war. Isn’t it?

A tour de force collaboration from two powerhouse writers that spans the whole of time and space.

"This book has it all: treachery and love, lyricism and gritty action, existential crisis and space-opera scope, not to mention time traveling superagents. Gladstone's and El-Mohtar's debut collaboration is a fireworks display from two very talented storytellers." Madeline Miller, award-winning author of Circe

"If Iain M. Banks and Gerard Manley Hopkins had ever been able to collaborate on a science fiction project, well, it wouldn't be half as much fun as this novella. There is all the pleasure of a long series, and all the details of a much larger world, presented in miniature here." Kelly Link

"[An] exquisitely crafted tale…. Part epistolary romance, part mind-blowing science fiction adventure, this dazzling story unfolds bit by bit, revealing layers of meaning as it plays with cause and effect, wildly imaginative technologies, and increasingly intricate wordplay… This short novel warrants multiple readings to fully unlock its complexities." Publishers Weekly (Starred Review)
