Book excerpt: In this sequel to Murphy and Mousetrap, Murphy and his three friends, Danny, Jeff and Albert, are making the transition from the tribal elementary school to the community middle school. They are all trying out for the middle school's soccer team, and they're pretty confident that The Formidable Four will all make the team. But once the tryouts begin, Albert, the tribal-school superstar, plays like a second-stringer. Murphy's new friend, Molly, is determined to help the boys find out what's wrong with Albert, but when they discover the truth, they realize that Albert is playing a whole different game.
