His Talisman by Cari Silverwood

CHARITY
Kidnapped and locked away forever. I’m too dangerous, for my testimony could destroy the CNC Fraternity.
I contemplate a lonely future … until the doctor gives me a choice: remain where I am or agree to be his toy and live on his private island.
Despite my fears, I say yes to him.
I refuse to be merely a doormat victim, this time.
When Cassius, an ex-military guard, arrives, the doctor invites him into the relationship. Yet Cassius warns me of murders and hints at terrible secrets.
From the first evening at the dinner table, I find myself in awe. I have been lured, hooked, and reeled in, one might say. I loved everything they did to me.
My tears and protests are clearly a thrill to them. They make me whimper and beg … and more, much more.
I have begun to explore the island to discover the truth.
My craving for pain and brutality? I can accept that, but am I falling for bad men?
Killers to the left of me, murderers to the right.
And here I am, stuck in the middle with you.
Dark unearthly secrets will be brought into the light.
