I preferred the first half over the second, but both were hard to swallow. These 6 ninth graders are smarter, more motivated, and more calm then any of the adults. They save the plane and then the world in a short time span, better than any adult could. Might be fun for kids to read, but not an adult. I wish it had been more plane and more realistic teens. I wouldn't recommend it to my 12 year old.
