Whistle's main theme throughout the series is soccer, but there is much more to it. This book is incredibly inspiring!
It's about Sho Kazamatsuri, he goes to a school call Musashinomori, but they won't let him play soccer as a regular because of his height. Sho decides that the best thing to do is to change schools. He transfers to Josui. His first day there he is treated like he is a pro player by the coach because she thinks that he is awesome because he plays for Musashinomori. She didn't realize he was just a substitute. Sho ends up practicing with them and humiliating himself because all he can do is dribble.
After that humiliating event, he decides to work extra hard no matter what. He practices hours and hours till he gets better. Tatsuya, one of the regulars actually the best one, runs through the park one day and sees him. Sho asks him to play and he does. The first game Sho lost badly, but he doesn't give up. The next day Sho asks Tatsuya to play with him and he gets the ball past him.
Sho has many challenges and to find out what they are you?ve got to read the book.
