Shotgun bride - Linda Lael Miller

All Mandy Sperring has ever wanted was to be a lady and live in a nice house. Instead she finds herself all alone in the little town of Indian Rock, disguised as a nun, and on the run from the brutal bounty hunter that killed her stepbrothers.

Kade McKettrick needs a wife. His older brother, Rafe, is married, but until he has a child, Kade knows that he still has a chance to inherit his father's ranch, the Triple M. Unfortunately, the only woman who really catches his eye is the pretty little nun staying in the hotel.

But when the bounty hunter, Pawnee Jim, learns Mandy's true identity, she runs to Kade for help. He offers to marry her and give her the protection of his family name and she agrees. But Pawnee Jim refuses to give up his prize, and his evil intentions might just end the burgeoning happiness between Kade and Mandy.
