The Horror At Camp JellyJam

My mom has been reading this book to me and we finished it tonight! It was cool. It's about a family just like ours. There's the mom and dad, and brother and sister. They are on a trip and are pulling a camper just like ours! The kids are bored and ask to ride in the camper while their parents drive...and they let them! We asked our parents if we could do that, and they said "No way!" They're in the camper being pulled up the mountain and the camper comes loose from the van! Things get even weirder after that!
