As the 2nd book of a series it is as good a read as the first. It continues where the first book ends and takes you on a wild ride that will have you staying up late to find out what happens next. I read the entire book in 2 days. I was captivated and totally enjoyed the story line and plot. You don't have to read the book series in order, but it sure helps. This book stands on it's own merits as quite a good read. I recommend this book to anyone interested in the subject of the Nephilim. If you have never heard of the Nephilim, then you NEED to read this book !
