Reminiscent of "Tunnel in the Sky".by Robert Heinlein this tale also is a bit like Stephen King's the mist, although I think both Heinlein and King do a better job with their stories. This book is more a tale of a summer camp turned to a survivalist camp as the kids are on their own after the brown mists changes everything they know. I think this should be listed more adult than young adult, but still found the book an interesting read.
