I got this for a friend's seven-year-old and will no doubt receive informed feedback in due course, as he's football mad - I'm not, but I did read it because I love children's books, and I was charmed I must say.
The premise reminded me of one of my all-time favourite movies, Big, with Tom Hanks (which interestingly was co-written by Anne Spielberg, sister of Steven, although Penny Marshall directed) and it's a neat premise because it has potential to take you anywhere. Frankie wins a beaten-up old football at a fairground and without giving the story away, the ball takes Frankie, his friends Charlie and Louise and his dog Max on a magical journey to the ocean main, where they have to win a game against a bunch of pirates in the Fantasy League if they are ever to return home..
I see that one reviewer here rather unfairly doubted whether it was written by Frank Lampard at all, which he should take as a compliment because he writes very well - writing for children requires discipline and quite a light touch, and IMHO he shows both. You can't help liking the hero - he loves his mum, insists on fair play and doesn't like to show off, although he has the skills.. My favourite line is where Charlie steps on Lou's console and cracks the screen. She thinks it's broken, and her dad always told her not to take it out of the house, so this is bad. Frankie puts his hand on her shoulder and says solemnly, 'It might still work.' Excellent :)
Whether I send for the rest of the series as the titles are released will depend on said feedback from seven-year-old, but I see there's one called Frankie vs the Cowboy's Crew, and that's mine because I may not be into football but I'm definitely into westerns.
