14 year-old Paul Winsome has to ride clouds to save his 11 year-old sister Vicki, and the solar system.  He has no idea how.  Why was he chosen?  Could anyone be less qualified? 

Through his parallel-imagined-life, Paul has to enter a dangerous, intimidating, puzzling pursuit of a reality just beyond his grasp.  He has no choice but to trust his imagination.  However, isn't his imagination mixed in with everyone else's in an imagination life stew?  Aren't his chances of failure literally astronomical? 

"Your gift of imagination is able to reach any altitude,” says wizard Maken Fairchild.  Easy for him to say.  He doesn't have to confront gargantuan gorilla Claude Nab or his owner, queen authority of malice Calamity Horrid.  He doesn't have to face invading solar system Vile Extinction, whose added suns will cook Earth upon her arrival. 

How does one ride clouds anyway? 

Surely someone has made a dreadful mistake.
