This is book 3 in the series and it was just as exciting as the previous book. Abel worthe has yet again added a new ghost, new structure, and new subject to the village. While trio is meeting the newest subject and figuring out their next move, there is a lot going on behind the scenes that they are unaware of. As abel worthe's experiment continues, his once well disciplined and dedicated staff is falling apart as there seems to be a loss in order and staff start taking matters into their own hands. With every battle and ghost the subjects face, you really get to see their strength and resiliency. As I'm reading i keep wondering just how much more can these characters take. This book will have you on the edge of your seat while rooting for the people trapped in the experiment to succeed.
