A great read for ages 9 (good reader) to 16. Although the main character is a boy, he is searching for his twin sister who disappeared a year ago. This book will appeal to both boys and girls.
It takes place in a dark future where all of civilization lives in England, on different levels. The poorer folk at the bottom level never see the sun and live in wet, unhealthy surroundings.
The book is full of adventure, video game references and lots of excitement. I can hardly wait for the next book!
