Query: Not part of the Ember series

The book itself was kinda of ok, but as part of the Ember series it was horrid. It only ties in on the last page. The entire story is preachy and anti-religious. I was excited to find out how the City of Ember was built, who was chosen to live in it, how they stocked it for two hundred years. The Prophet of Yonwood did not address any of these plot elements. This book is not a decent stand alone book. Instead, it was combined with the Ember series because it was the only way it would sell. Do not waste your time, skip this book and go on to book four of the series.
