On an ordinary day, at an air show like that in any small town across the country, a plane crashes into a crowd of spectators, killing and injuring dozens. But when the dust clears, a thirteen-year-old girl named Ava is found huddled beneath a pocket of rubble with her best friend, Wash. He is injured and bleeding, and when Ava places her hands over him, his wounds miraculously disappear. Ava has a unique gift: she can heal others of their physical ailments. Until the air show tragedy, her gift was a secret. But now the whole world knows, and suddenly Ava is thrust into the spotlight. People from all over the globe begin flocking to her small town, looking for healing and eager to glimpse the wonder of a miracle. But Ava's unusual ability comes at a great cost—her own health—and as she grows weaker with each healing, Ava begins searching for an escape. Wash agrees to help Ava, but little does she know he has his own secret he's been harboring, and soon Ava finds herself having to decide just how much she's willing to sacrifice in order to save the one she loves most.
