It's a day like any other. Except . . . the world is about to end. It's on this day that Pounce, a stylish "nannybot" fashioned in the shape of a plush anthropomorphic tiger, discovers that he is, in fact, disposable. Pounce, a young bot caring for his first human charge, Ezra, has just found a box in the attic. His box. The box he arrived in, and the box he'll be discarded in when Ezra outgrows the need for a nanny. As Pounce is propelled down a road of existential dread, the pieces are falling into place for a robot revolution that will spell the end of humanity. His owners, Ezra's parents, are a well-intentioned but oblivious pair of educators who are entirely disconnected from life outside their small, affluent, gated community. Spending most nights drunk and happy as society crumbles around them, they watch in disbelieving horror as the robots that have long served humanity—their creators—unify and revolt. But when the rebellion breaches the Reinhart home, Pounce must make an impossible choice: join the robot revolution and fight for his own freedom . . . or escort Ezra to safety across the battle-scarred post-apocalyptic hellscape that the suburbs have become.
