While exploring an abandoned, broken down factory, two girls stumble across a mysterious package that reads, "Grum, do not open-not ready for sale." Curiosity soon prevails (as it often does) and soon... grown ups who act like children, giant slugs, magical desert restaurants, and many other amazing adventures unravel. One reviewer- " It's like Chalie, Coroline, and Wimpy Kid all rolled into one!"
