Since joining the Beijing International Academy for Martial Arts, Matt James and his new friends have become crime-fighting adventurers. Now it seems they're in for more crime-busting action as they prepare to compete against the Kyoto Institute of Excellence. A pupil at the Institute is seeking deadly revenge and the Tigers must lie in wait to prevent disaster. Can they strike before it's too late?
A great pick for readers who love getting lost in a good story.
