Time was

Annabelle Donohoe, the CEO of World Tech, is mad as hell. Her dreams of world domination died the day Zac Robillard discovered her evil plans and fled World Tech, taking his greatest creation, his beloved I-Bots, and all his research, with him. (Read about their origins in Isaac Asimov's History of I-Bots!) More than super-machines, more than robots, the I-Bots are eerily human in appearance, but not in abilities. Their genetic components--based on human DNA--and mechanical infrastructures give them pshyical strength and powers humans can only imagine, and a measure of free will impossible in robots. Annabelle wants them back and will stop at nothing to get her way, including hiring the world's deadliest assassin to find Zac, and his I-Bots--the beautiful Radiant and Killaine, clever Itazura, Psy-4, and Stonewall--and bring them in...or kill them. For if Annabelle cannot have the I-Bots she vows that no one else can either. But Janus, the ruthless killer, is not the only hunter they must elude...Surrounded by enemies, Zac and the I-Bots can find no safe place, not even the streets. In the year 2013, the Silver Metal Stompers, a neo-Nazi gang, roam the nation's cities wreaking havoc on robots, especially Scrappers, outmoded homeless robots who huddle in hobo camps, rusting away unless they are repaired by a mysterious humanitarian and robotarian called DocScrap.
