I am a fan of Christine Feehan's "Drake Sisters" Series of books, so when this one popped up I figured I'd give it a try.  I didn't realize that it was a series (#7) and having never read any of her GhostWalkers books I can happily say that I didn't have any trouble following the plot line.  The characters were defined enough for me to understand each well enough to enjoy the story.  I loved the concept of these "enhanced" warriors with special powers and the involvement of our govt. is always intriguing...however, I do have to say that the sex scenes were a little to much.  Very male dominated..sex replacing words of love..blah, blah, blah.  Typical over the top sex scenes that were really unnecessary to the "love story" portion of the plot.  Even with that bit of criticism, I enjoyed the book enough to purchase the first book in the GhostWalkers series to read next.
