Something about the amber lights I saw in my head for the lighting throughout this book made me remember the intensity of playing around after dark in the far corners of shopping parking lots. I don't care for the following books, but this first book in the series was amazing.
The City of Ember Series by Jeanne DuPrau. Age: 13+. Score: The series itself gets a 100, but individually, I'd say that Ember and People of Sparks both get a 90, Prophet of Yonwood gets a 60, and Diamond of Darkhold gets a 100.
