Callypso Lillis is a siren with a very big problem, one that stretches up her arm and far into her past.

For the last seven years Callie has been wearing a bracelet of black beads up her wrist, magical IOUs for favors she once received. Only death or repayment will fulfill her obligations.

Everyone knows that if you need a favor, you go to the Bargainer to make it happen. He's a man who can get you anything you want … at a price. And everyone knows that sooner or later he always collects. But for Callie, he's never asked for repayment. Not until now.

When Callie finds the Bargainer in her room, a grin on his lips and a twinkle in his eye, she knows things are about to change. At first it's admitting a truth—a single bead's worth—acknowledging the attraction between them. But the Bargainer is after more than just rekindling their connection. Something is happening in the Otherworld. Fae warriors are going missing one by one, and only the women are returned, each in a glass casket, a child clutched to her breast.

For the Bargainer to save his people, he'll need the help of the siren he spurned long ago. If she can forgive him.

The Flesh and Fire series is set in the beloved Blood and Ash world.

Born shrouded in the veil of the Primals, a Maiden as the Fates promised, Seraphena Mierel’s future has never been hers. Chosen before birth to uphold the desperate deal her ancestor struck to save his people, Sera must leave behind her life and offer herself to the Primal of Death as his Consort.

However, Sera’s real destiny is the most closely guarded secret in all of Lasania—she’s not the well protected Maiden but an assassin with one mission—one target. Make the Primal of Death fall in love, become his weakness, and then…end him. If she fails, she dooms her kingdom to a slow demise at the hands of the Rot.

Sera has always known what she is. Chosen. Consort. Assassin. Weapon. A specter never fully formed yet drenched in blood. A monster. Until him. Until the Primal of Death’s unexpected words and deeds chase away the darkness gathering inside her. And his seductive touch ignites a passion she’s never allowed herself to feel and cannot feel for him. But Sera has never had a choice. Either way, her life is forfeit—it always has been, as she has been forever touched by Life and Death.
