51y9vv1LFvL._SX324_BO1,204,203,200_This is a classic on prayer.  Bounds was a chaplain during the civil war.  He does not write from a perspective of theoretical ivory tower doctrine.  He writes from a man who is literally on the front lines of a life and death battle and leading his men into a life of prayer.  Many wonderful nuggets on prayer.
