What's a devil to do? Satan's desperate to retire. He needs an heir, and he's turning to the promise of his three beautiful, bold, smart, and irresistibly sexy daughters.

Jezebel, the half-demon? Or Lola, the soulstealing baby of the family? The challenge is on and one must prevail-unless they're thwarted by that powerful human emotion called love.
