A Reason to Kill — Eric A. Shelman

FRANK SWANSON IS A SERIAL KILLER. Frank Swanson has always been on the move ... a transient serial killer with his own reasons, his own justifications for who he is and what he does. But when Frank meets a strange, beautiful woman named Olivia Rainey one quiet Texas night, he must analyze his inner demons more closely than ever before. His chance encounter with Olivia spins his life quickly out of control, for she has secret demons of her own. In this case, what Frank Swanson doesn't know just might kill him.
