Final Storm The Conclusion

A girl, a werewolf, and a demon walk into a bar. Unfortunately, they're all the same person with an enraged vampire hot on their heels.

Being possessed by the Demon of Lust sure amplifies a werewolf's secret crush on a certain vampire Guardian. Cellica Scott may be tied to his bed, but Christoph's harsh growls and meager resistance crumble to dust under the beast's erotic seduction. With her initial transition fast approaching and the demon's control becoming tougher to combat, Cellica escapes and embarks on a terrifying journey with a furious vampire nipping at her neck.
 
Christoph Nox's first loyalty is to his queen, the notoriously sarcastic Halfling, with a prophecy to uphold. The last thing he needed was to babysit his best friend's spirited little sister possessed by a Prince of Hell. The werewolf's wanton behavior drives him mad with lust, and the need to mark her as his has become an obsession.

With the insatiable pull of the mate bond ripping him apart, his friendship with the Werewolf King hanging in the balance, the queen's birth of the first Daywalker King transforms into life-or-death. Will Nox get to Cellica before her pending transformation forever binds her soul to the demon? Or will Abigail—the witch with the ability to slaughter them all—destroy his reason for living? 

Author's Note: If things like violence, blood, gore, references to rape, consensual BDSM play with intense sexual scenes, menage play, graphic language, and demons are issues for you, then move along; this is NOT the book for you. In fact, my entire Storm series is NOT for you.
If it is, welcome to my sick mind.
