Bodyguard (Shifters Unbound) (Unabridged‪)‬

Elizabeth Chapman is saved from an armed robber by a giant Kodiak bear who shifts into a large, well-muscled, and fully naked human male. But when it's revealed that the robber is the brother of a dangerous criminal, Elizabeth finds herself the target of a vendetta. 

Ronan, the Bear Shifter, takes her to Shiftertown for safety, where Elizabeth learns that the mateless Ronan, alone in the world, takes care of Shifters who have also been left on their own. Having grown up in foster care, Elizabeth can only admire how protective Ronan is. 

But Ronan will only let Elizabeth leave the confines of Shiftertown if he becomes her 24/7 bodyguard. Elizabeth chafes at her restriction, but agrees. The trouble is, the sassy human Elizabeth is triggering Ronan's long-buried need to find himself a mate.
