Book excerpt: Having (not) mastered cricket, soccer, rugby, taekwondo, track & field, swimming, golf, basketball and tennis, Marcus gives AFL a go in this very funny tenth book in the series. Marcus is a maths whiz who is not good at sport. His dad is a self-help author who thinks Marcus can achieve anything he sets his mind to, with hilarious results. In illustrated diary format, Marcus's gentle, satiric humour and comic drawings will have readers laughing out loud while learning a surprising amount about sport.
