Happy birthday to me. When he tastes my blood, he finally understands I'm mortal. And I realize we have something in common: we both crave revenge. So we make a deal: I can stay in the forbidden city to hunt for my mom's killer. In return, I'll help him get the vengeance he craves. I just have to pose as a sexy succubus. One problem--he's my number one suspect. And that's increasingly hard to remember as he teaches me my role: seduction. With each heated touch I drift further into peril. And if I fall under his seductive spell, death awaits me.
