I read a book called Soccer Sabotage by Liam O'Donnell, on Epic. The story was about this girl named Nadia. She is playing for her local soccer team, and they have made it to the national tournament--against some very determined opposition. The other team has someone push their coach down the stairs and puts their coach in the hospital. The girls have no choice but to continue to play without a coach. It is really hard for them because the other team starts sabotaging them with pranks that can kill someone. The girls make it to the game and win the game without their coach. Their coach is very proud of how good they were.
Hope this helps!!!
