Endangered by Michelle Larkin

Boston beat cop Aspen Wolfe gets the surprise of her life when she learns she’s a shapeshifter. Her abilities awaken as a ruthless regime unleashes its troops to eradicate the shapeshifter population.

Forced to run or be hunted, Aspen meets Dr. Tora Madigan—a beautiful and resourceful shapeshifter who oversees an underground sanctuary. Her attraction to Tora is a welcome distraction, but the fierce lioness plays hard to get. Together they discover that Aspen is a powerful shapeshifter thought to be extinct. Her existence gives shapeshifters everywhere a fighting chance. But there’s one small problem: she doesn’t even know how to shift.

With no one else up for the job, Tora agrees to train her. Aspen soon finds herself leading a group of extraordinary shapeshifters who are willing to risk everything to save their species. When the sanctuary is targeted for annihilation, she must come up with a game plan. Fast.
