Strange Liberty

Salvo Caine, a young man cursed with a magically sapping touch, is convicted of manslaughter and dispatched to an island prison. Once there, he's offered limited freedom - and affection - by the cold and manipulative prison warden, Guillaume Villiers.

Rated M, 27.5k, dark fantasy with some M/M dark romance on the side. Good bit of age gap sexiness, and some medical and care-giving kink as well.
