In Tommy Greenwald’s Dinged, the companion novel to the acclaimed hit Game Changer, a star football player watches his father deteriorate from injuries he suffered playing the very same sport.

Caleb Springer is the up-and-coming star freshman quarterback on the high school football team, which isn’t a surprise considering his dad, Sammy Springer, was an NFL superstar and is now the town celebrity. College scouts are already snooping around Caleb, and his future seems set.

But just as Caleb’s glory days begin, his dad starts to change. He’s forgetting things and getting angry at random times. Caleb is soon forced to confront a bleak possibility: The sport that gives him so much status and self-worth might be the cause of his dad’s strange behavior. Will Caleb keep playing the sport of his dreams, even if he knows how dangerous it can be?

“A talented high school quarterback weighs gridiron glory against the scary possibility of permanent brain damage... A cogent cautionary tale.” —Kirkus
