Angel on My Back — David Estes

Archangel Gabriel contacts Earth to find Jake Hannity, a ne'er-do-well who thinks the weight of his problems is greater than anyone else's. Gabriel's boss, the Commander of the Universe, "has need of" Hannity, to transform him from what he is to what he might become-if he performs certain assignments for people less fortunate than he. Hannity spars with Gabriel's voice, which only he can hear, and reluctantly agrees in order to get that angel off his back.
