The Cruel Guardian by Isabella Starling

My dark guardian lavishes me with expensive gifts… but now he wants so much more.
I’ve lived my life in seclusion, sheltered, hidden and taught to be obedient.
Every year on my birthday, my guardian comes to visit.
My parents say he’s cruel, vicious and unforgiving, but all I see is a man who wants to give me everything.
But on the night of my seventeenth birthday, everything changes…
He says I’m no longer a little girl, and the time has come for him to collect his debts.
And this debt is one only I can pay for.

The Cruel Guardian is the short prequel to the Kingpin’s Property trilogy. It is not a standalone book.
