Recap: Book 1, Pleasure Unbound, is about Eichelon and his mate Tayla (hate that name, BTW). Book 2, Desire Unchained, centers around Shade and his mate Runa. Both good books with hot, hot scenes.
Book 3, Passion Unleashed, is Wraith and Serena's story. Wraith has been poisoned by an assassin, and the poison has no antidote; Wraith does not have long to live. They learn about a "charmed one", Serena, who is charmed to live forever, and can only give up her charm through sex. No biggie, good thing Wraith's an Incubus, right? He ends up develping feelings for Serena, and can't go through with her seduction. Instead he wants to protect her from the demons who are trying to get the charm and kill her. The problem is that while he is spending time with Serena, the underworld is falling into chaos and the hospital is literally falling apart. Then Eichelon makes a discovery that has Wraith rethinking his decision not to seduce Serena.
This book was great! I love Wraith and Serena's story. Their feelings for each other were so strong, I was almost in tears near the end - I didn't see how there could possibly be a HEA. I also liked Gem and Kynan's side story, and the introduction of a new character will make for an interesting storyline later.
I had wondered what all the hubub was surrounding this series - now I know. Can't wait for Ecstasy Unveiled!
