As the only one in the family without magic, Makeda has decided to move out on her own and make a life for herself among the claypicken humans. But when her father goes missing, Makeda will have to find her own power--and reconcile with her twin sister, Abby-if she's to have a hope of saving him . . .
 *We'd had to be cut free of our mother's womb. She'd never have been able to push the two-headed sport that was me and Abby out the usual way. Abby and I were fused, you see. Conjoined twins. Abby's head, torso and left arm protruded from my chest. But here's the real kicker; Abby had the magic, I didn't. Far as the Family was concerned, Abby was one of them, though cursed, as I was, with the tragic flaw of mortality.*
