With her mother gone away in an attempt to recover, June’s dad sends her off to math camp in an effort to reintegrate her with her peers. A farewell note convinces June that her dad can’t make it without her and sneaks off the bus to return home. In the forest she discovers Wonderland as a physical place, but it’s not the version from her imagination. Instead, the park has fallen into disrepair and is being dismantled by rogue plushies (Chimpanzombies) and a gathering storm known as “the darkness.”
