A great story for 7-11 year olds, with a link to Dr Jekyll and Mr Hyde, but much funnier! The humour would definitely appeal to that age group. This is the second book in the series and sees the unconventional teacher Mr Hyde with his class on a school trip to a new theme park. There are many excellent characters from Mrs Blunt, the headmistress and teacher's pet Amelia, to Jake and his assorted classmates. The excitable and popular Mr Hyde has an unbelievable secret that the children must help him manage, in order to keep his job, but it always causes complete mayhem! The twist with the owner of the theme park and the school reports as an afterword were a clever addition to this story
