ZJ's father, "Zachariah 44," is a famous NFL football player. ZJ loves his dad, and occasionally feels the weight of the spotlight as his son, especially as he considers whether football is a sport for him. ZJ's dad has taken many hits to the head throughout his career, but he's always gotten back up and gone back into the game he loves. Now, however, those hits seem to be catching up to him, and what starts as a temporary pause from playing soon marks the end to Zachariah's career. It's confusing and scary for ZJ to see his dad's agonizing headaches and small memory lapses deteriorate into mood swings, personality changes, aggression, depression, and terrible memory loss. Sometimes his dad doesn't even recognize ZJ as his son. Doctors aren't sure what's wrong, and worse, they're not sure how to help. As his dad's condition worsens, ZJ finds comfort in memories-of good times with his dad, before things started to change-and in the support of his mom and the friends who stick with his family, including ZJ's own three best friends. This novel-in-verse is set in the early 2000s, before much was widely known about CTE (chronic traumatic encephalopathy) and the risks posed to players in the NFL. Despite the heartbreak of what is happening to ZJ's dad, moments of joy and love shine through. (Ages 9-13)
