Emily is the spunky little princess of Greenwood, a lush forest where gigantic cedars rise up over a hundred feet high. The creatures of Greenwood are elves, gnomes, Shinnybins (master tree-climbers who have suction-cup-like hands and feet,) and Grumphs, who burrow their lairs beneath the big tree roots. Emily’s castle, the Green Palace, is a massive treehouse, accessible only by vine swings and ropes. Like her sisters, the Emerald Princess has a magical friend Arden, her unicorn. And she has a special power given to her by the wizard of the Jewel Kingdom.
