Brutal Limits by Marissa Farrar

Limits are blurred, boundaries are broken, and now the game is real.
When I took the job on the island retreat known as The Limit, I hadn’t expected to be mistaken for someone else.
Someone who wanted to be chased, to be caught, to be corrupted.
It was a mistake that would lead four men to take my innocence. Brody, Wilder, Rafferty, and Asher. They each have their own secrets and pain, and I’d started to think I was cracking through their armor.
But the connections we’d made vanished the moment they discovered my lie.
Now everything changes.
What began as a game has become something else entirely. Something sinister and dangerous. Now there are no rules. No limits. No get out clause.
No escape.
I ran from one threat right into the arms of another and now I don’t know if I’ll ever be free.
