The Obsidian Gene — Robert Wilson

The Obsidian Gene treats its readers to an intense storyline featuring the most horrendous type of predator -- a pedophile who kills to protect his secrets. Ronald Brasher is drawn from the thousands of wealthy American men who now travel to foreign countries where they can safely subject helpless street children to their appalling perversions. After murdering his parents for their winning lottery ticket, he travels into Mexico in his palatial RV, where he enlists the aid of a remarkable young boy from the streets to help him find homeless girls who fit his special desires. Meanwhile, his sister, Samantha, has figured out intuitively and without proof that he is responsible for the murders. When Ronald returns to San Antonio to silence her, he sends the unsuspecting children to do his killing for him. Samantha's lover, Cliff, an undercover ATF agent who is preparing to testify at an upcoming trial, gets caught in the middle of the crossfire. FBI and ATF agents protectively surround their witness in the mistaken assumption that attempts made on Samantha's life are in actuality against their man. That leaves the way clear for Ronald Brasher to hunt down his sister so that he can destroy all connections to him for their parents' murders. Two San Antonio homicide detectives come to Samantha's aid. But are they too late?
