By Blood Alone (Legion)

The new techno-thriller from the author of Legion of the Damned and The Final Battle, it takes more than guts to win a war. It's Legionnaire against Legionnaire in a struggle that will be won by strength, by courage, and fittingly so, by blood alone. In a Legion gone lax, Colonel Bill Booly, with his mixed blood and by-the-book attitude, is a misfit. So when he steps on some important toes, his punishment is assignment to the worst post in the galaxy: Earth. But Booly and his troops will turn out to be Earth's best line of defense, when a Legion-led military coup topples the government.

Maybe I've been reading too much combat fiction recently and need a change of scenery. Or perhaps its just that this book isn't as good as the last two (Legion of the Damned and The Final Battle). The characters aren't the strongest, and the plot is weaker than the previous two books. On the other hand, I did finish the book, and don't regret reading it. Oh, the cliff hanger ending is annoying too.
