Summary: Lucy is excited to learn how to code in a new after-school club. Her best friend, Anjali, is part of the theater club, and Lucy doesn’t have any coding friends. When she gets an anonymous note written in code, she enlists some of the other girls from the club to try to help her solve the mystery. With the help of her older brother Alex, Lucy and her three new friends create a game that eventually reveals the identity of the note writer. By the time the mystery is solved, the four have formed a friendship and are ready to move along to book #2. 144 pages; grades 3-6.
Pros: Two books about girls coding in the same week! This one manages to sneak a few coding lessons into a book about friendship that coders and non-coders (and soon-to-be coders) will all enjoy. Written by the creator of the Girls Who Code movement (www.girlswhocode.com) that is starting coding clubs for girls all over North America.
Cons: Anjali seemed like an extraneous character.
