Fearing arrest, she escapes Nevada to Texas to take a job for the sexiest cowboy she's ever seen. Slowly, Amber's memories resurface, and Luke offers to help solve the mystery of the dead guy.

Working with the FBI, she and Luke must uncover the real killer before she gets Luke and his daughter killed.
