The Miscalculations of Lightning Girl by Stacy McAnulty
Lucy Callahan was struck by lightning when she was 7 and is now a genius-level math whiz. After being home schooled since the incident 4 years ago, Lucy feels ready to go to college. But her Nana has a different plan for her...middle school. If she wants to enroll in college, Lucy must complete Nana's four requirements: go to 7th grade for 1 year, make 1 friend, join 1 activity, and read 1 book that is not a math textbook. Can Lucy make it through the year?
