A timid robot will risk everything to protect his favorite human in a post-apocalyptic world.

Block, the CleanerBot who risked it all to safeguard a baby girl across the war-torn wastelands, thinks he's finally found a safe haven for Wally. But the humans he's entrusted with her care won't let him visit her, leaving him to follow his cleaning routines and miss her more every day.

Robot Found Family in Danger

When the humans are forced to surrender Wally to militaristic SoldierBots or face extermination, Block will do anything to keep her safe… even if that means aligning with a former enemy, a colossal Mech, and their motley army of renegade robots.

Together, they must face down dangerous SoldierBots, fleets of attack drones, and WarBots that will stop at nothing to claim the child in this action-packed science fiction adventure. Wally holds the key to humanity's survival—or their doom—in this thought-provoking work of speculative fiction.
