Query: A crude, tasteless start

Full disclosure: I only read up to page 33. This might disqualify me as a reviewer. On the other hand, I can't think of the last time I stopped reading a book this quickly, even a terrible one. What's more, the jingoistic U-S-A tone of the book is actually a nice attraction for me. So what's the problem? First, lame and stereotypical dialogue. Second, a crude and tasteless sex scene. It's tough to turn me off with a sex scene, but this one managed it in spades. I recommend skipping this series and going straight to Jack Campbell's Dauntless series. Besides its other merits, Campbell's series has a great opening that gets you into the action right away.
