Savage Chains: Scarred (Men In Chains 1.6)

Angelica has a choice: leave the vampire BDSM club where she was held captive and sold as a sex slave, or stay and help Reyes bring down the men who captured her.  But if she stays, she must help Reyes complete his undercover mission by posing as his sex slave...which brings her deeper into the perilous underground world of vampire sex clubs. 

What she never expects is to get lost in the sensuality of the clubs...and lose herself in her role as Reyes' captive. But there's no disguising the brutality of the sex-slave community, and soon Angela begins to question whether Reyes is really who he says he is...and where she belongs.
