Cuff Master (Ink and Kink #4)
Frances Stockton

Inviting her for a moonlit walk, Ethan kisses Morgan and her seduction begins, until a teenaged ghost interrupts. Ethan is skeptical of the supernatural, but if he doesn’t open his mind he may never collar the woman he loves.
As they work together to solve a cold case, Ethan introduces Morgan to the very dark, seductive world of sex, submission, bondage and dungeons. All the while, danger is growing. If Ethan doesn’t find a young girl’s killer soon, all could be lost.
Reader Advisory: Morgan’s sexual awakening includes watching a scorching-hot brief scene of male/male lust, with Ethan by her side.
