About the book: year / This is the war of the 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 don't trust anyone anymore... To stop the demons, purebred vampire princess Morgan Labeau agrees to a treaty proposed by werewolf alpha Jace Vaughn. She would become his mate, share her blood with him... and in return, the wolves would help the vampires in this battle. The enemy of my enemy is my husband... But Morgan doesn't understand how dangerous wolves can really be. Jace had been waiting for years for the 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.
