My first instinct is to say Travis Bagwell has outdone himself. but the webs woven through the 5 books of the main timeline are far too intricate and delicious to be approached as a simple sequel. This tale was largely planned from the beginning and Book 5 does not disappoint.
Great story, great action, intrigue and character development are all here. If you are familiar with Travis’ work, buying this book is a foregone conclusion.
if you are not, I strongly recommend going back to Book 1. It is a wild ride and you will love it.
