The Story Shapers: A Book About Being a Brave, Bold Creator

When Billy and Mary sneak into a dusty old attic, the last thing they expect to find is a rat named Bart that's given up on his dreams. Every story he's ever started to write refuses to follow the rules, so he's hidden himself away and given up.  As they transform into Bug & Bear, the kids help Bart see that his rediculous characters, wandering plots, and chaotic colors are just what this world needs to create the magic we've all been waiting for.
