Stacy McAnulty is the author of many books for young readers, including chapter book series The Dino Files and GoldieBlox and picture books including Excellent Ed, 101 Reasons Why I’m NOT Taking a Bath, and Beautiful. A former mechanical engineer, Stacy writes about math and science with authority. The Miscalculations of Lightning Girl (Random House Books for Young Readers) is her middle-grade debut. A lightning strike gave her a super power…but even a super genius can’t solve the problem of middle school. Lucy Callahan was struck by lightning. She doesn’t remember it, but it changed her life forever. The zap gave her genius-level math skills, and ever since, Lucy has been homeschooled. Now, at 12 years old, she’s technically ready for college. She just has to pass 1 more test–middle school! Lucy’s grandma insists: Go to middle school for 1 year. Make 1 friend. Join 1 activity. And read 1 book (that’s not a math textbook!). Lucy’s not sure what a girl who does calculus homework for fun can possibly learn in 7th grade. She has everything she needs at home, where nobody can make fun of her rigid routines or her superpowered brain. The equation of Lucy’s life has already been solved. Unless there’s been a miscalculation?
