Author Brad Herzog brings his well-received prose and soccer knowledge together with Melanie Rose's charming and realistic illustrations to detail every facet of the game. Each letter has a simple rhyme for young readers: "J is for the Jerseys that soccer players wear. But often in the World Cup, opponents tend to share. In a gesture of respect after a game ends, They simply swap their jerseys as if they are old friends." For older readers the expository text gives specific details about goaltending, referees, the World Cup, and many other aspects. K is for Kick follows the wildly popular Z is for Zamboni.
