James Henry Trotter lives with his cruel aunts Spiker and Sponge until one day the barren, old peach tree in their yard produces a single peach that grows to nearly the size of a house. When James takes a closer look at the enormous fruit, he discovers a tunnel that leads him to the peach pit where he meets a rag-tag band of human-sized, talking invertebrates: an old green grasshopper, a centipede, an earthworm, a spider, a ladybird, a glowworm, and a silkworm. These bugs become James’ companions on an adventure that will take them over land and sea! And as they travel James learns important lessons about courage, friendship. and seagulls.
