What sets humans apart from cyborgs? Sixteen-year-old Jeremy Q. Taylor is about to find out. After losing his mother the year before, Jeremy feels more alone than ever. Then his dad surprises Jeremy with a new "brother." Addison is a cyborg, who looks to be about eighteen. But he's not just any cyborg. He's almost perfect in every way. When the plans to mass-produce the cyborg are sold to a robotics company, things get complicated. Can they reverse engineer the cyborg? What if something goes wrong? The possibility of this occurring creates fear and anger in those who have grown to love Addison. Going into hiding may be his only chance to survive.
