When James Henry Trotter accidentally drops some magic crystals by the old peach tree, strange things start to happen. The peach at the top of the tree begins to grow, and before long it's as big as a house. Then James discovers a secret entranceway into the fruit, and when he crawls inside, he meets a bunch of marvelous oversized friends—Old-Green-Grasshopper, Centipede, Ladybug, Miss Spider, and more.
After years of feeling like an outsider in the house of his despicable Aunt Sponge and Aunt Spiker, James has finally found a place where he belongs. With a snip of the stem, the peach starts rolling away, and the exciting adventure begins!
