Enter the Lair by Tia Didmon

When the huntress becomes the prey…

Sarah Marksmen doesn’t miss. As a Park Ranger, she is tasked with hunting down the cougar responsible for multiple attacks and kills. She expects the cold welcome of the Cascade family when she arrives on their land. She doesn’t expect the blistering heat she experiences with Devon Cascade.
As dark forces converge to annihilate everything she holds dear. Will she be able to trust in a man who was forced to harden his heart, or will she be the catalyst that destroys an entire species?
