Although this is listed as a prequel to the Maze Runner series, it does not have any of the characters from Maze Runner except the last 3 pages - which is really unnecessary. The first 2/3 of the book is well developed & descriptive. Unfortunately the end of the book seems rushed & the author in a hurry to wrap things up with a simplistic ending thats anticlimactic at best. But after reading the whole series, I should have realized that as Dashner's weakness. He did the samething in book #3 of the trilogy.
