A joint American/Canadian Black Ops team ventures through a wormhole and gets their asses handed to them by a Dark Elf and her forces. It was a little bit Stargate in the Underdark, and I say that as a compliment. The task force retreats, but the fae seelie don't take kindly to the intrusion--especially when they once ruled on Earth. They send a spy through the remains of the inter-dimensional portal, and that's when things get interesting.
The story follows several different characters, all of whom are well developed and interesting. Not all of them are likeable, one in particular irritated me quite a bit, but I get the feeling she's meant to be annoying. I can't say that I felt for the characters all that much, but I still enjoyed their company. The action is amazing. The author has incorporated his military experience into the story in an impeccable manner. It's almost as informative as it is entertaining. There were times when the prose seemed to contain a little too much detail, but I think that's something a lot of military fans will like.
All in all, this is a fascinating, fast-paced book, and I loved it. The only complaint I have is that there were a few minor inconsistencies related to the characters actions (The dark elf dismounts from Gazekiller, but later the story continues as though this never happened). The magic vs technology angle is a lot of fun to read, and I thought the identity of the Ancient Ones made for a clever twist. The book reads well as a standalone, but I'm keen to see how the series develops after the events in this book.
