Cheeky and her crew hunt the galaxy's most dangerous extremists: Core AI sympathizers who want to eliminate all organic life. Half the crew of Sabrina are AIs themselves—fighting against their own kind to protect their friends.

When a nightclub infiltration on Illium goes sideways, AI operative Sabs goes deep undercover to infiltrate the local cell. But when she vanishes into abandoned tunnels beneath the city, the team loses her signal at a hub with twenty-seven possible exits.

With only hours before Sabs is moved to an unknown location, Cheeky must mount a desperate extraction. What Sabs discovered changes everything: this isn't just one cell. It's a network spanning the galaxy—and they're building something that could doom billions.
