Roebuck’s Revenge, by Michael Shapiro

Raf Vella found a corner of the gray market he figured would be a quiet and safe place to call home. Working for a massive underground warehouse for scarce goods, he’s spent years keeping his head down and his daughter, Olivia, out of trouble. But his fragile equilibrium shatters when his old nemesis, Shawn Roebuck, reaches out from a prison cell with a devastating video implicating his daughter in a criminal smuggling ring.

This is no ordinary threat—Roebuck’s army of sentient AI bots is spreading chaos through Raf’s gray-market operation, hijacking inventory, shutting down systems, and even infiltrating human minds. As the bots evolve, targeting Raf and Olivia in increasingly terrifying ways, Raf must navigate a treacherous underground economy, confront rogue scientists, opportunistic televangelists, and elite bot jockeys, and wrestle with a consciousness no longer entirely his own.
