Miku is going to School Camp in the forest, with her friend Cait and the rest of her class. It should be fun. But Miku has premonitions of danger, and when Oscar goes down with a festering rash, and a rushing wind blows out the bonfire she's sure something bad is going on. Then Alex finds the frog-like Filth-Licker in the boys' toilets. Can Miku save her friends from the evil that is rising? And what about the Fith Licker? Whose side is he really on?
