Project Cain by Geoffrey Girard

A thrilling YA companion to S&S Touchstone's Cain's Blood, releasing simultaneously.

Fifteen-year-old Jeff Jacobson had never heard of Jeffrey Dahmer, the infamous serial killer who brutally murdered seventeen people more than twenty years ago.

But Jeff's life changes forever when the man he'd thought was his father hands him a government file telling him he was constructed in a laboratory only seven years ago, part of a top-secret government cloning experiment called 'Project CAIN.' There, he was created entirely from Jeffrey Dahmer's DNA. There are others like Jeff -- those genetically engineered directly from the most notorious murderers of all time: The Son of Sam, The Boston Strangler, Ted Bundy... even other Jeffrey Dahmer clones. Some raised, like Jeff, in caring family environments; others within homes that mimicked the horrific early lives of the men they were created from.

When the most dangerous boys are set free by the geneticist who created them, the summer of killing begins. Worse, these same teens now hold a secret weapon even more dangerous than the terrible evil they carry within. Only Jeff can help track the clones down before it's too late.

But will he catch the 'monsters' before becoming one himself?
