This is a war of immortals...Vampires and werewolves have been blood enemies for many centuries, but now a new threat has arisen...demons have escaped from hell and seek to destroy both species.When you no longer trust anyone...To stop the demons, purebred vampire princess Morgan Labo agrees to the agreement proposed by the werewolf alpha Jace Vaughn. She will become his mate, share her blood with him... and in return, the wolves will help the vampires in this battle. The enemy of my enemy is my husband... But Morgan does not understand how dangerous wolves can really be. Jace had been waiting for years for his chance to claim her. The werewolf lured his princess into a trap, and now that she has fallen into it, he does not intend to let go. He would send the demons back to hell and keep his vampire by his side forever. Because they are connected by blood ties.
