I love this book and have read it to every Year 4 I have ever taught. It is about a boy called Barney who, along with his sister Lou, stays with Granny during the holidays. As Barney explores the ‘chalk pit’ he falls into the dump and is greeted by Stig, a very real caveman. No-one believes that Stig is real of course. The story follows their adventures – escaped circus animals, burglary, inventions, the ‘Snarget’ boys – and the chapters are the perfect length for one reading aloud session.
