Callypso Lillis is a siren with a very big problem. For the last seven years she’s been collecting a bracelet of black beads up her wrist, magical IOUs for favors she’s received. Only death or repayment will fulfill the obligations. Everyone knows that if you need a favor, you go to the Bargainer to make it happen…but at a price. And everyone knows that sooner or later he always collects. But for one of his clients, he’s never asked for repayment. Not until now. When Callie finds the fae king of the night in her room, a grin on his lips and a twinkle in his eye, she knows things are about to change. For the Bargainer, it’s more than just a matter of rekindling an old romance. Something is happening in the Otherworld. There are the whispers of an evil that’s been awoken. If the Bargainer has any hope to save his people, he’ll need the help of the siren he spurned long ago. Only, his foe has a taste for exotic creatures, and Callie just happens to be one...
