Girls FC is the best team for football and friendship. In book 11, Amy's story, the girls are delighted when their team is invited to New York to play in a high school league tournament. But ten-year-old Amy Minter is more interested in Macy's department store than the football pitch. She can't understand why her team-mates are getting so annoyed - it's not her fault she prefers shopping and flirting to football. Women's football is the fastest growing sport in the world. In the UK, one million girls play and more than 9,000 girls' teams are registered with the FA. In 2010 Walker Books paired up with the English Schools Football Association, which reaches out to 30,000 girls and 6,000 teachers, to make Girls FC the official sponsor of its National Under 11s Girls seven-a-side cup.
