When ten-year-old Byron Boon Barnett boards a rocket-ship for a move to
the Moon with his family (and his irritating robot, Jose Ignacio), he's
expecting the time of his life in the lunar colony of Cosmopolis. What
he's not expecting is a stellar disaster that'll demolish Cosmopolis
before lunch. Boon insists he knows how to survive it, but people tend
not to believe him about stuff. His parents have been lecturing him on
the dividing line between using his imagination for fun and using it as
an excuse for bad behavior. Suddenly it's the dividing line between life
and death.
