I love this book it’s soooo good it’s about 2 kids Doon and Lina who are living in a underground city and it is dyeing the generator has started to fail and they are running out of supplies. Than Lina finds a paper, instructions for egress so Doon and Lina team up to follow the instructions but while they are doing this they find out they the mayor is hoarding supplies now they have to convince everyone that he really is bad. They are now wanted criminals they finally find what they are looking for and escape. Now they are in the outside world, and they leave a message telling the other people of ember how to escape.
Jeanne DuPrau did a outstanding job on this book although I think it would have been best alone she didn’t have to add the other books. Anyhow her writing is so original I think everyone who loves adventure a mystery should read this book.
