The authors of Kickoff! are twins and former NFL players Tiki and Ronde Barber. Tiki was a running back for the New York Giants and three-time Pro Bowl selection. Ronde was a cornerback for the Tampa bay Buccaneers, four-time Pro Bowl selection, and Super Bowl winner.
This story is inspired by their childhood. The twins are starting Junior High and worried about the harder homework, making new friends, and not being in class with each other. But their biggest concern is making the football team. I bet they make the team since they did go on to be NFL players after all but read to book to hear more of their story!
