The Isle of Sin and Shadows by Keri Lake

This island alone boasts more ghost stories than all of Louisiana, combined. And I’m one of them.

In the Louisiana swamplands, ghost stories are as much a part of childhood as chasing fireflies and crawfishing. They never much scared me, though, nor the possibility of evil out to do me harm. Until the night I watched shadows come to life and butcher everything I loved.
With a stranger’s help, I managed to escape to an isolated place miles north, and, in time, became my own ghost story. A cautionary tale for the locals. Nearly a decade passed, before I returned to my birthplace, in hopes of unearthing long-awaited answers. Instead, I found something I wasn’t looking for. Someone. A remedy for my loneliness.
Or so I thought.
Turns out, Thierry Bergeron is no elixir. He’s a deadly poison, cursed by the demons of his past, and feared by those who call him the elusive Rougarou of the bayou. A devious rogue, whose seductive whispers and rough hands haunt my dreams. The big bad wolf that defiles me without apology, or remorse. I should resist him, but I can’t.And when the shadows return to stake their claim on me, his darkness is the only safe place to hide.
