Regin after seeing Declan knows that her lover has returned but she does not try to make him remember everything as it would take his life once again. Declan starts a campaign against the immortals and is completely unaware that he is also one of them. War, love, and fulfillment of the promise, Kresley Cole has added everything in the story.
More complete than Pleasure of a Dark Prince: Immortals After Dark, Book 9 and narrated better than A Hunger Like No Other: Immortals After Dark, Book 2 by Robert Petkoff. The return of the warrior again and again to the world was the most interesting thing in the novel. Though Aidan lost his memory whenever he and Regin come face to face we can feel the fire burning. The two just cannot resist the temptation which rises when they come closer.
