Love is ten kinds a crazy, right? Let me put it to you this way: if you can get away, run, don't walk. Because once you're exposed, you'll never get a siren out of your head. Some loves are cursed. Others are ... dangerous. Especially the love between wannabe rocker and quarter incubus, Wesley "Link" Lincoln, and dark caster, siren, and bonafide bad girl, Ridley Duchannes. But now Ridley is missing, and Link was with her--right up until she vanished. Determined to find her, Link reunites with his New York bandmates and the mysterious Lennox Gates, who wants Rid for himself. Together they travel to the Deep South, find the crossroads where blues guitarist Robert Johnson made his deal with the devil, discover a menagerie of casters locked in cages, and uncover an evil in New Orleans that threatens to destroy them all. This time, love might not be enough.
