Prey Island by Sorcha Black

In this tropical paradise, the games are rough and the women never win.
Signing a one-month contract allowing rich, brutish men to prey on me isn’t a wholesome way to earn a scholarship for my sister, but desperate times call for reckless measures.
Keeping a low profile is no longer an option when Ajax and Calder start targeting me. Sure, they’re hot, but they’re also twisted and mean, and won’t leave me alone. To make matters worse, every time they claim me for themselves I learn something new and shameful about my deepest, most deviant fantasies.
But they’re not the only threat on this island.
Sacrificing my body may be inevitable, but sacrificing my life wasn’t in the contract.
