The Hidden Moon - J. S. Keim - Bog

Twelve-year-old Jack Coughlin and his younger brother find a small wooden box that's supposed to hold magic. Instead of flying to the Space Center in Florida like Jack wants, the genie-like figure inside mistakenly sends them and a friend to outer space. On the eerie, hidden moon of Anron, where things are not what they seem and flying dragons carry them into battle, Jack must figure out a way to get them all home safely. An exciting adventure story for middle-grade boys and girls.
