In a subterranean laboratory on Monpetit Island a hologram of the earth floats above a silver platform. On a beach just a few steps away Anna Atom is about to go for her usual afternoon swim. Island life is idyllic: it is always beach weather! But Anna's mom spends most of her days in the lab, monitoring the environmental conditions of the earth. It is one such crisis that sets off a chain of events that takes Anna away from her peaceful island to the ends of the earth.
