Wicked

Gunned down after a bank robbery, Cad Rankin is offered a chance to save his soul if he can save a troubled western town from its lawless ways, a mission that seems hopeless until he meets convent-raised Amy Lattimer.
Although she'd been educated in a convent school, Amy was determined to do anything to locate her missing father, including posing as a fancy lady. Then she found an ally in Cad Rankin, who wasn't about to let her become a fallen angel. But even as Amy longed to surrender to Cad's touch, she began to suspect that he had a secret that stood between them and unending bliss.
