Shaw by Milly Taiden

Panther shifter Poppy Cain has been living a secret life. She’s been hiding her nursing career from an overbearing uncle and terrifying cousins. They run a shady business in town, and when they want to use her as a pawn, Poppy makes a hard decision: run. What she didn’t expect was to find a mate in the process. Shit just got real.
Shaw Eagan uses his hacking skills for good. Or in the very least, he toes the line. But when the evil Cain family pushes him over the edge, he comes up with a dangerous plan. He clears their bank accounts and steals a mysterious serum to turn himself into a shifter. His family depends on it.
When they meet by pure coincidence, sparks fly. Poppy’s life is in danger, she has no time for a mate. And Shaw doesn’t know she’s a Cain. The truth is exposed. Lives are threatened. Trust is on the line. Can Poppy and Shaw put away their pain long enough to survive?
