Guilty as Sin (Phoenix Rising #4)

Book four in the Phoenix Rising series. Michael's bad, bad, bad-all the way to the bone. A single heated encounter with the master thief, and level-headed Liseriel the Gray has never been so furious-so intrigued-in her life. Neither has Michael. Danger's always been his drug of choice. With his huge bronze wings and sweet, serious smile, Daxariel the Burnished is everything the thief is not-a generous, shining spirit; an honest, loving soul-and a virgin. It's going to take two Aetherii to catch a thief. Lise and Dax are both so godsbedamned good, Michael can't wait to debauch and defile, to make his Aetherii beg for dark erotic pleasures. It's the only way he knows to win-and win he must, because there's something about wings and tails and trust freely given that has him reeling. Exquisitely trapped between Michael's intoxicating wickedness and Dax's steadfast love, everything Lise believes about duty is dust on the wind. How can she crave both these men, different as night and day?
