Spark in the Underground City

Four centuries after The Last War scorched the planet, human life endures in the Underground City—a totalitarian society where intimacy is outlawed and laboratory breeding has erased the concept of family.

Nineteen-year-old Spark, an Outsider, infiltrates the city in search of her missing younger brother. She meets Drill, an aging rebel haunted by his past, and Alaska, his android protector. Drill offers his team of outcasts to assist Spark in her search. Utah, a humanoid bot, and Mian, a free human, compete for Spark’s attention.

As she peels back layers of terrible secrets, Spark comes face to face with Citizen One, the immortal dictator responsible for the design of the brutal society. If Spark is successful at rescuing her brother, she may bring down the entire government.
Dark, haunting, yet bittersweet, Spark in the Underground City explores the meaning of family and friendship, and the line between human and AI machine.
