When two friends compete, one of them will be forced out.

Joey and Zach have always been best friends. They're also two of the best baseball players in their league, and shoo-ins for the all-star team at the end of the season. Their dream is to play together on the Center State select team, and they will do anything to help each other get there.

So when Zach is forced to go on an extra-credit field trip that would make him miss the championship game, Joey comes up with a risky plan to bail him out. Everything should be fine?as long as no one finds out what they did.

Then the unthinkable happens: The boys learn there's only one open spot on the select team. In this tense, action-packed story, former NFL defensive end Tim Green brings us the kids who will push themselves to the limit to compete?even if it means putting everything on the line.

Tim Green, for many years a star defensive end with the Atlanta Falcons, is a man of many talents. He's the author of such gripping books for adults as the New York Times bestselling The Dark Side of the Game and American Outrage. Tim graduated covaledictorian from Syracuse University and was a first-round draft pick. He later earned his law degree with honors, and he has also worked as an NFL commentator for FOX Sports and NPR.

His first book for young readers, Football Genius, inspired in part by his players and his own kids, became a New York Times bestseller and was followed by Football Hero, Football Champ, The Big Time, and Deep Zone. He drew on his experiences playing and coaching Little League for Rivals and Pinch Hit and two more New York Times bestsellers: Baseball Great and Best of the Best.

Bestselling author Jon Scieszka called Tim Green's Unstoppable, a book about a boy's struggle with cancer that debuted at #2 on the New York Times bestseller list, "Absolutely heroic. And something every guy should read."

Tim Green lives with his wife, Illyssa, and their five children in upstate New York.
