This book is about a boy who goes to sleep and travels back in time to meet Romans, Vikings and Celts and has lots of adventures.
My favourite part is when Jack, the little boy, has dinner with the Celts, because the Celts are interesting.
I also like it when Jack goes back in time at the the end of the story and ends up in an air-raid with a girl called Betty. I like it because it is frightening.
It think it is funny when, after Jack has dinner with the Celts, he says he is going to have a little nap and ends up waking up in his bedroom. His dad is trying to wake him and Jack says "is that the Celts?" and he says "No, it's your dad!"
I've learnt that if i'm ever in an air-raid i should go to a shelter.
