Dungeon Daddy by Jane Henry

His protection comes at a price: total submission.

Rae: Imprisoned in my tower, shut away from the world, I lived in the pages of my books–and my fantasies.Then he rescued me. Made me his.
He becomes the best Daddy I’ve ever known–caring yet stern.
Ryder: Kept captive her whole life, she’s the perfect combination of beauty and innocence.
I bring her to Limits, the high-end, exclusive, members-only Club… my home.
Now she’s under my roof and my protection.
I’ll protect her, keep her safe…
All she has to do is obey.
