Book excerpt: Key Selling Points Shows that exercise is for everyone, emphasizes collaboration even in competition and encourages empathy, as Jordan realizes his "rival", Ivan, is actually just a shy new kid. The school's Massey Obstacle Olympics (MOO) is a take on the grueling Tough Mudder endurance event, complete with unexpected rain and mud for Jordan to contend with. The third early chapter book featuring Jordan and Max, this book continues the gentle exploration of gender performance and identity. Suzanne Sutherland's debut novel was an ALA Rainbow Book List selection; like Jordan, she got into running as a "decidedly unathletic" kid and loves it to this day. There are 22 black-and-white illustrations throughout.
