Before Midnight is a twisted Cinderella tale with humor, magic, and a lot of bite. Loupe has her hands full slaving away for her bloodthirsty stepfamily, skinning the wolves her stepmother and stepsisters hunt despite the royal family’s strict laws against such slaughter. It takes the last vestiges of her inner strength to keep her secret hidden, the secret that slashes its way out of her body under the light of the full moon. She doesn’t have the energy left to act on the desire stirred by the prince with the hungry eyes…or the obnoxious, but well-meaning pixie with the magic to bring them together.
 
But when a cursed prince needs a werewolf to help him preserve all that he is and ever has been, he doesn’t take no for an answer. Etienne will find the beautiful werewolf with the power to save him, no matter whose blood must be spilled to make it happen.
 
A grand ball. The stroke of twelve. A magic “slipper.” All kinds of things can happen when you don’t leave the ball…Before Midnight.
