Showing Caine's Reckoning by Sarah McCarty

Caine Allen is a hardened Texas Ranger, definitely not the marrying kind. But when he rescues a kidnapped woman and returns her to town, the preacher calls in a favor. One Caine's honor won't let him refuse. From the moment he beds Desi, Caine knows turmoil will follow. Desi might have the face of a temptress, but she also has a will of iron and while she needs his protection, she's determined that no man will control her again.

They establish an uneasy bond, but it isn't enough for Caine. He wants all Desi has to offer. He wants her screams, her moans, her demands. . . everything. Yet there's still a bounty on Desi's head, and keeping her sexually satisfied is proving easier than keeping her alive.
