Red City by Michaela Haze

Welcome to the Red City.
You belong to the demons now.
Prison has not been kind to the girl who could paint the future.
When Doe is given the opportunity to serve the rest of her life sentence in the confines of the Red City, without bars, she does not hesitate.
Demons rule the walled city, and humans are for food, pleasure or servitude.
When Doe is purchased at an auction by the Pink Sector, the sordid territory of the Incubi and Succubi, she is thrown into a world unlike anything she has ever seen.
Her new master hates her, without reason. The harem is full of beautiful viperous women.
There is an insane Demon in the wine cellar of the mansion, who claims that she is his soul mate.
Something deeper is going on, and snapshots of the future won’t help.
Can Doe stay alive or will the Demons chew her up and spit her out like so many before her.
Will the Wilde brothers, her new masters, be enough to save her from herself?
