Grace and Tippi. Tippi and Grace. Two sisters. Two hearts. Two dreams. Two lives. But one body. Grace and Tippi are conjoined twins, joined at the waist, defying the odds of survival for sixteen years. They share everything, and they are everything to each other. They would never imagine being apart. For them, that would be the real tragedy. But something is happening to them. Something they hoped would never happen. And Grace doesn’t want to admit it. Not even to Tippi. How long can they hide from the truth—how long before they must face the most impossible choice of their lives?
