Grace loves cats. She also loves taking pictures of cats and drawing Not-So Super comics. She doesn't like Sammy Stringer, a boy in her class. She's got lots and lots of ideas, and when her neighbor's cat goes missing, Grace does her best to make Mrs. Luther feel less lonely. But as the mystery of the missing cat continues, Grace's well-intentioned plan backfires, and she finds herself in a bit of trouble. Maybe, just maybe, Sammy Stringer will help her through.
