It's just another day on the Scrap: lose the last of your credits at the WarDome, dodge the gangs and religious fanatics, discover you can destroy electronics with your mind, stumble upon the deadliest robot ever built When Eve finds the ruins of an android boy named Ezekiel in the scrap pile she calls home, her entire world comes crashing down. With her best friend and her robotic sidekick in tow, she and Ezekiel will trek across deserts of irradiated glass, battle cyborg assassins, and scour abandoned megacities to save the ones she loves and learn the dark secrets of her past.

Lemon Fresh has seen better days. After the climactic battle in Babel, she finds herself separated from Ezekiel and Cricket in the wastelands. Lemon’s abilities to manipulate electricity mark her as a deviate, and deadly corporate operatives are hunting her to use as a weapon in the war between BioMaas Incorporated and Daedelus Technologies. Instead, Lemon finds herself falling in with a group of fellow deviates—a band of teenagers with astonishing abilities, led by an enigmatic figure known as the Major, who may hold the secrets to Lemon’s past. Meanwhile, Cricket finds himself in possession of the puritanical Brotherhood, a religious cult set for a head-on collision with the Major and his band. Searching for Lemon, Ezekiel finds a strange ally in an old enemy, and uncovers a plot that may see him reunited with his beloved Ana. And inside Babel, a remade Eve hatches a plan to bring an end to the world.

From the bestselling co-author of the Illuminae Files comes the thrilling finale in the LIFEL1K3 trilogy—hailed by Marie Lu as "a breathless, action-packed exploration of what humanity really means." Best friends have become enemies. Lovers have become strangers. And deciding whose side you're on could be the difference between life and death. For Eve and Lemon, discovering the truth about themselves—and each other—was too much for their friendship to take. But with the country on the brink of a new world war—this time between the BioMaas swarm at CityHive and Daedalus' army at Megopolis, loyalties will be pushed to the brink, unlikely alliances will form and with them, betrayals. But the threat doesn't stop there, because the lifelikes are determined to access the program that will set every robot free, a task requiring both Eve and Ana, the girl she was created to replace. In the end, violent clashes and heartbreaking choices reveal the true heroes . . . and they may not be who you think they are.
