As an overworked employee of the Ministry of Magic, a husband, and a father, Harry Potter struggles with a past that refuses to stay where it belongs while his youngest son, Albus, finds the weight of the family legacy difficult to bear.

When James accidentally spills some magic crocodile tongues near an old peach tree, one of the peaches grows as huge as a house. James discovers a secret entranceway into this peach, where he befriends the insects that live inside of it. When the stem snaps off of the tree, the peach starts rolling away, and James and his friends begin to have exciting adventures.
