This is a adventure book about 5 students who are completely different to each other also who hated each other, they got chosen to go on a trip together. The trip was to a cave, which they got trapped inside, the teacher fainted during the most of the time, so they have to carry the teacher and solve the problems to get out of the cave.
I actually don't really like this story, but the characteristic of each characters is good, a punk girl, a fat shy girl, a bully, a weak and a know-everything. I liked the punk girl the most, she is really cool, I liked the way how she do things. The beginning of the book was catchy but the ending was too rush, I don't even know how did the symbols and all the things come from. The ending was just too random, it's like suddenly it just ended. I think younger kids will like this book better.
