I can not wait to read the sequel! This book contained so much imagination and interesting plots it was wonderful. The underground city of Ember was a very very well thought up city and it had everything. Even the unkown regions. Doon Harrow and Lina Mayfleet are well made characters and make a great pair in fighting against the mayors scandals. This book made me eager to turn the page and read what would happen next. Everything would fall into place with clues and hints of how to get out of Ember, the failing city. Slowly but surely the pair find clues as to how to get out, clues that are un noticable until later in the story and are quite tricky to put together. Everything that happens is so interesting and never boring or predictable. An excellent read!
