By Blood Alone — William C. Dietz

PART HUMAN.
PART ALIEN.
ALL HERO.

In a Ton gone ax, Colonel Bill Booly, with his mixed-blood and by-the-book attitude, is a misfit. So when he steps on some important toes, the brass is quick to make him pay. His punishment: assignment to the worst post in the galaxy.

Fort Mosby, Earth. Home of the 13th Half-Brigade, a collection of the Legion's rogues and rejects.

But Booly and his troublemaking troops will turn out to be Earth's best line of defense when a Legion-led military coup topples the government.

It's Legionnaire against Legionnaire in a struggle that will be won by strength, by courage, and...BY BLOOD ALONE
