Bloodlines - Shifters of Rishard, #1

They have been here for centuries. War destroyed their planet, and now they hide among us. Malcolm Donovan, a dragon shifter, rules over one of four clans. When a clan member is murdered, he must find the killer. Nothing will disrupt his pledge to protect his clan. Nothing that is until he finds his mate. Elsie Monroe, human to the bone, and the resort manager for the Donovan family finds herself falling in love with the charming Wyoming town, and she can't help but be drawn to the mysterious Malcolm Donovan.
His rude attitude is atrocious, but his kisses can bring chocolate to a boiling point. Not to mention what he does to her body and heart. Soon Elsie is dragged into a world of secrecy and violence. Creatures she thought were fantasy are actually real. And she is left wondering if love will be enough to capture and tame her own personal dragon.
