Moon Knight by Huston, Benson & Hurwitz Omnibus

Once, Marc Spector was the Egyptian god Khonshu's avatar on Earth. Now, Spector and Khonshu are at odds. Moon Knight desperately wants to get back in the hero game, but every battle pushes him closer to the edge -- both in brutality and sanity! As the increasingly unstable Moon Knight tries to navigate the super hero Civil War, he finds himself in the sights of Norman Osborn's Thunderbolts! Spector must take refuge far away, in one of his multiple personas -- but the lure of vengeance is too strong to keep him away for long. Can Moon Knight reclaim his heroic ideals, or will he succumb to the shadows -- and end up back under Khonshu's thrall?
