It's vacation time for Jessica Davies and her family, but Jessica is anything but happy about it. Forced out of school for a week in early autumn by her inconsiderate parents, Jessica must endure some long and boring days on a houseboat. There, on this floating prison, her very gross and infuriating kid brother severely complicates Jessica's life. Adventure comes by way of a small frog in an old shoebox. Follow out to the mudbank and listen in on the music.
