Keeper of the Crystals: #1 Eve and the Runaway Unicorn

Eve is staying with her grandmother and her only choice in playmate is Oscar, the boy from next door. The lure of the forbidden attic in her Nan's house proves too much for Eve and Oscar and they sneak upstairs to explore. When Eve finds a small crystal figurine of a unicorn it acts as a portal into another world. Eve and Oscar find themselves in the desert of Panthor where unicorns are now enslaved, land turned to desert and people forced to become desert nomads. How can Eve and Oscar survive in a land where panthers and people communicate and where an evil king has complete control of every living being? More importantly, how will they ever get home again?
