Instinct

Siren was taken by Dirk three years ago because he'd thought she was a Senser, shifters created by the Fates. She's been his plaything in his Club Posh ever since, hoping that one day she'll break free.

Xavier, leader of the Sensers, is in mating frenzy, and when he's sees Siren, she has no hope of escape. When he finds out she's human, hated by the Sensers for their treachery, things don't go as he planned.

They'll have to find a way through it if they ever want to be happy, and Siren just may be something more.
