Kallisti

Three fifteen-year-olds hunting for geodes in the desert and coming across a mirage of a forest might be bizarre enough. But when a woman appears in the forest and throws a golden apple into the sand before the mirage blinks and vanishes, Kree, Pip and India soon find themselves with the power to pause time. Idunna, the Norse Goddess of Spring and Rejuvenation, grows the mythical apples that provide the Gods with youth and immortality. Tricked by Loki, she loses her supply of apples, and urgently discards the Kallisti - an all-powerful golden apple created by the Gods - to keep it from enemy hands. Idunna plans to retrieve the apple, without knowing that the teens have already spotted it. Kree, Pip and India discover that simply holding the golden apple and saying 'stop' and 'go' will pause and restart time. . . a pretty amazing thing to be able to do, especially when you accidentally prevent a robbery and save a man's life. This opens their eyes to the possibilities of the good they could do with the apple. They soon realize, however, that even good deeds and the best intentions can sometimes come at a price.
