Billy's Brain Booster Juice

Billy Radcliffe has a miserable life. His classmates bully him, the teachers call him a wally and his Poker-playing mother is too busy collecting three-of-a-kind to notice.

But one lunchtime, Billy finds a mysterious recipe buried in a muddy corner of the school playground. It's a recipe for Auntie Brenda's Brain Booster Juice and it turns him into a genius overnight.

Can Billy defeat the school bullies with the help of his marvellous recipe? And is being a super-genius really as super as he thinks?
