Beloved Possession: Organized Crime by Leona Windwalker

Ishmael Lux.
A name synonymous with wealth. The elite come to him- to stay in his hotels and to play in his club, both for business and for pleasure. He has a secret, though. It’s rather an open one, though believed by most to be rumour and speculation.
Kristoffer Jones.
A new hire of Triborr Property Management International, one of Lux’s many legitimate fronts. He was thrilled to be in London, straight on the heels of being informed he was being moved onto the management track. Some rumours are best left unconfirmed, as he discovers when he finds himself in the wrong place, at the wrong time.
Ishmael sees it as an opportunity.
As with all opportunities that will pay off handsomely, he takes it. Then, he locks Kris away. Kristoffer is his and he is never going to let him go.
The kicker?
Kris is rapidly becoming unsure if he wants to be free.
