Judge is desperate. His mother has threatened to send him to a different school next year--away from his twin brother and "posse" of friends. To prove he can succeed at his current school, Judge needs to bring up his grades. After weeks of hard work--all while dealing with his sometimes difficult brother, his dyslexia, and the news that his divorced father has decided to remarry--Judge's hopes depend on winning a science competition. Soon it all comes down to the egg-drop . . .
