Life can be hard as an orphan at Mending Hearts Children's Home, but Abicus Turne is no ordinary orphan. A nefarious trick that results in tragedy causes Abicus to discover his ability to 'slide back' in time and change the past. But he quickly learns that changing the past can have unintended consequences. At the Spring Festival, events spin out of control and expose a secret plot by enemies that would destroy the world. Aided by genius younger sister Binny, street-wise Bosh, and sweet-talking Kendra, Abicus and his fellow 'castaway' orphans race to open mysterious time locks hidden by his parents. Within them lies the key to saving their future. But can Abicus find it in time to also save their past?
