This was a great middle grade book. Max is an impulsive, quick-tempered girl who likes modifying electrical gadgets, likes superheroes, & uses a wheelchair. She is being raised by her Grandpa, Toppy, who is the town's police chief, and when Max gets in trouble he makes her write essays about sappy movies on the Sentimental Flicks Channel. Wonderful characters and a good haunted-house-style mystery.
