Twelve-year-old Kristian McNeal has depended on his twin, Gracie, to fight most of his life. He’d never admit he didn't know what he'd do without her. After stealing his mother’s golden heart heirloom, he's swept from danger and transported to a planet where he discovers he’s been chosen to fulfill his mother’s destiny. However, a sinister shadow threatens to destroy the planet of his heritage in the Tri-fold Galaxy, along with his family unless he finds the key that unlocks the secret to the golden heart. Will he follow his own heart and summon the courage to fight the battle of his life to save his heritage, or will he cower in the face of danger and depend on his sister for help one more time?
