The Water And The Wild

For as long as Lottie can remember, the only people who seem to care about her have been her best friend, Eliot, and the mysterious letter-writer who sends her birthday gifts. But now strange things and people are arriving on the island Lottie calls home, and Eliot's getting sicker, with a disease the doctors have given up trying to cure. Lottie doesn't know what she can possibly do - until a door opens in the apple tree. Down through the roots is another world - a world of treacherous, beautiful, impossible magic that just might lead to a cure for Eliot.
