I really enjoyed this book's plot and thought it was very imaginative. The book starts out a little slow but soon it becomes more exciting and fast paced.The book is about Lina and Doon, two twelve-year-old children who both have the urge to leave the depressing underground city of Ember that is quickly running out of food, paper, pencils, and many other necessities. The power from the generator is starting to fail with the outages becoming more and more frequent. Together Lina and Doon try to unlock the secret of how to leave Ember before the power stops once and for all they are plunged into darkness forever.The City of Ember is a really good book and makes you appreciate the little things.... like the sun!!
