Sixteen-year-old Jeff Jacobson had never heard of Jeffrey Dahmer, the infamous serial killer who brutally murdererd seventeen people more than twenty years ago. But then Jeff discovers he was constructed in a laboratory only eight years ago, part of a top-secret government cloning experiment called Project CAIN. And scientists created him entirely from Jeffrey Dahmer's DNA.
Jeff isn't the only teenage serial-killer clone. Others have been genetically engineered using the DNA of the Son of Sam, the Boston Strangler, and Ted Bundy. Some clones were raised, like Jeff, in caring family environments; others within homes that mimicked the horrific early lives of the serial killers they were created from.
When the most dangerous of the boys are set free, the summer of killing begins. Worse, they hold a secret weapon even more deadly than the terrible evil they carry within.
Can Jeff help catch the "monsters" before becoming one himself?
