A Gray Crusade - The Rogue Series, #2

After Silas Knight's daring live message from New York City, the world is in a precarious place. Demonstrations, protests, and riots flood the streets, with a resounding message: rogues are people, too. Grayson agrees. But unlike the uneducated populace, he's seen things that no living man should have to see. He's been behind enemy lines, in the midst of the darkest and most depraved oppressive regime in history.
And he knows something so dark, so terrible that it pains him to carry that knowledge day after day. He knows that in order to secure freedom, Silas Knight must die. Even if his friends must die along with him.
