My son Dan - age 8 - says:
"If you're really posh like the prime minister or the queen and dont like disgusting things you shouldn't read this book. Fleabag and his disgusting friends are on a mission to stop Moldfinger from taking over the world with a giant mushroom. This is the most gross-out Fleabag book yet. They get captured but always escape. The pictures of the Mexicans always make me laugh. I got this book a few days ago but I'm already half way through because it's so good. It's really suspensing! and funny in a gross-out way."
I (Dan's mum) agree - though I think it would do the PM good to read it as well. Great combination of excellent cartoon illustrations, disgustingly funny text and pacy plot makes this particularly good for getting boys reading, though my daughter enjoys the Fleabag books too. As do I.
