Have Snakes, Need Birds

Sergeant John Mackenzie is on his third deployment to Iraq at the height of combat operations. His overriding goal: get his soldiers home safely. That mission is difficult enough when every day is a fight against snipers, roadside bombs, or just plain old boredom-it becomes impossible when John accidentally awakens two ancient spirits, each bent on destroying the other, collateral damage be damned.
A soul-collecting demon named Moonlit Samuel wants to move up in the hierarchy of evil; a malevolent force of nature known only as taliment destroys everything it touches; and John still faces local insurgents, foreign fighters, a belligerent battalion commander, a greenhorn lieutenant, and questions of his own sanity.
John must find a way to protect his men, save the city, and return to the woman he loves before she becomes just another victim of supernatural combat.
