Steel Defender (Rusted Wasteland, #2)

Can a kind-hearted robot protect his favorite human from being erased?
Block has finally found a safe place for Wally—the baby girl he safeguarded across the war-torn wastelands—or so he thinks. But the wary humans he’s entrusted with her care won’t let him visit her, so he follows his cleaning routines and misses her more every day.

When the humans are forced to surrender Wally to supercomputer Mach X’s lethal 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 militaristic SoldierBots, attack drones, and WarBots that will stop at nothing to claim the child. She holds the key to humanity’s survival—or their doom.

If you enjoy robots with a heart like WALL-E plus the action-packed adventure of Transformers, Robocop, and Terminator, you’ll love the second book of this thrilling post-apocalyptic sci-fi series.
