Book 3 of the Vampire Kingdom series.
When Lila opens her eyes, she's no longer in Sebastian's palace. She's being held prisoner by someone else now—someone far scarier than the vampire prince who she's fallen in love with.
The worst part about it all is that her vampire captor wants her dead. Lila knows that if she doesn't find a way out and fast, there's a very good chance that they'll get their way.
