As All-UK Knitting champion, 17-year-old Ben Fletcher has won himself a paid trip to New York, and to the U.S. National KnitFair. Unfortunately, his new girlfriend Megan is unable to join him, which means Ben has the dubious pleasure of being accompanied by his family and his third-choice-friend Gex. The other problem is, Ben's not really sure he wants to be known as a teenage knitting genius any more. His idea for a knitable hoodie could make him millions . . . or turn him into a laughing stock forever.
