Counterfeit Son is a 2000 novel by Elaine Marie Alphin and was written for young adults.

His "Pop", Hank, is a serial killer who preys on young boys, murdering more than 20 over the years.

When "Pop" dies in a gunfight with police, Cameron takes on the identity of this boy, Neil Lacey, a victim who was abducted and murdered six years earlier.

The Lacey parents accept "Neil" into their home with few questions, but he lives in fear that he will make a serious mistake through not knowing Neil's likes and dislikes and that dental records and suspicious Detective Simmons will expose him.

Alphin describes the years of sexual and physical abuse that Cameron endured at the hands of his father, but never in graphic detail.
