For a third grader, Sophie Simon is one smart cookie. She enjoys teaching herself advanced calculus and has performed successful heart surgery on an earthworm. She's also very clever when it comes to dealing with her clueless parents. But Sophie is no genius when it comes to calculating the high value of friendship -- until, that is, she has to use her incredible IQ to help out some classmates with their own parental troubles.
"Through a series of lively and humorous events, Sophie ends up with something she hadn't counted on–friends. The reading level is perfect for those who have already transitioned to easy chapter books but want a higher vocabulary and plot complexity. The story concludes with 'Sophie Simon's Encyclopedia of Things She Can't Believe You Don't Know Already,' which is a glossary of terms and phrases used in the book." -- Janet Weber, School Library Journal
