Shadow's seduction / Kresley Cole.

"Prince Mirceo Daciano and his new friend, Caspion the Tracker, comb the streets of Dacia, drunkenly seeking out pleasures of the flesh. In what should have been a typical night, they coax a bevy of nymphs to bed. To impress their females, the demon and the vampire kiss on a dare. Once they finally break away from their soul-searing kiss, they find themselves alone and shaken. Had they imagined their explosive chemistry? Obstacles, ranging from a death sentence to exile in a war-torn dimension, threaten to destroy their lives and the vulnerable promise in that one kiss. Even if Mirceo accepts Caspion as his fated mate, the seductive vampire still must convince the stubborn demon that their bond is forever. Any royal Dacian union must receive the blessing of King Lothaire, an unpredictable and savage killer." -- Provided by publisher.
