In my book there is a boy and his father. Book starts with these boy and father's adventure. They are trying to find interesting things and they find something interesting. When they found something they give each other their opinion. The man always think hisself. For example the child asked the man will you give it to museum, but the man said 'No, for my collection.' This man love tunnels very much and I think this man's love of tunnels effected on his son , so his son loves tunnels too. I think the son prefer tunnels to his school. Because I remember a sentence like he does not like to school. Also we can say he is not really popular at school and his grades are not seem good. When they are in tunnels they found sometimes very old railway, or they found someone's office. Not only someone's office but also a paper which is very important in someone's office. The man also like about the rock,stone. I think he collects rock,stones and I think he has a big collection. This book is adventure and exiciting because the tunnels are not really safe because tunnels can collapse like a earthquake and they can die. It is possible to collapse because these railway and other things are very oldrock,stones and I think he has a big collection. This book is adventure and exiciting because the tunnelsare not really safe because tunnels can collapse like a earthquake and they can die.
