The Shifter by Jade Hayes

What do you do when your whole life is a lie?

A month ago, Penny Dimas’s biggest worry was how she would pay for car repairs. Then a visit from an estate lawyer upended her entire life, thrusting her into a world fraught with danger and myth. Alone and trying to navigate her new reality, she turns to hunky police detective Ty Farris for help. The man is the size of a mountain, beautiful, and the only thing standing between her and certain death.
Ty knew when he received the call about Theo Davis’s death something was hinky. When the man’s beautiful, long-lost niece shows up and people try to kill them, he longer has to wonder what that is. Her tale is farfetched, but he can’t deny what he witnesses with his own eyes.
On the run as they try to uncover who wants them dead, they discover a world where humans and gods collide with deadly consequences.
