As the enemy AI grows stronger, the world is more deadly… Block must do everything in his power to track down Wally, the little girl he cares for. But how does a harmless CleanerBot infiltrate the deadly SoldierBots who hold her captive? Block and his motley crew of renegade robots journey across war-ravaged wastelands to track Wally down in a desperate race against human and AI foes. The ominous super-intelligence Mach X has devastating plans for Wally. If you enjoy characters full of heart and page-turning adventures, then you’ll love the third book of this post-apocalyptic sci-fi series and its robot main character.

Considerable progress has been made in the past 20 years toward understanding the basic mechanisms of corrosion, and the application of this knowledge to its control. From the very beginning, educational institutions and industrial research laboratories have contributed greatly toward determining and elucidating the fundamental principles of corrosion reactions. Some of the basic principles involved in cor rosion of metals can be credited to early investigators. Michael Faraday in 1830-1840 studied the relationship between the quantity of a metal dissolved and the electric current which was produced by this reaction. He also proposed that the passivation of iron was through the formation of a film and that the dissolution of a metal was electro chemical in nature. Sir Humphrey Davy in 1824 worked out the funda mentals of galvanic corrosion of ships' hulls and applied sacrificial zinc anodes to protect them from sea water corrosion. Richard Arlie in 1847 demonstrated that corrosion produced by oxygen at the surface of iron in a flowing stream generated a current. With the fundamental knowledge available to him from these early investigators, Willis Rodney Whitney developed and expressed, in its most useful form, one of the basic scientific principles which provides modern corrosion specialists with a fundamental basis of corrosion control. Dr. Whitney concluded that corrosion of iron is electrochemical, and that the rate is simply a function of the electromotive force and resistance of the circuit.

Can a timid robot keep his favorite human alive? 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 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 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, fleets of 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 characters with heart and page-turning adventures, then you’ll love the second book of this post-apocalyptic sci-fi series and its robot main character.
