Query: Look out Tom Clancy!

It must be tough as a new writer getting noticed in the action thriller genre, but I'm glad I found this book. Not only has Stephen Hannemann hit the mark with the story - action packed, compelling and several twists and turns - but he has done a fantastic job of character development and bringing scenes to life. As another reviewer put it "a thriller with heart". I am giving this 5 stars for exceeding my expectations. Great job!
