MISSION to HELLJust yesterday, Sergeant Gil MacDonald and his APC crew had been fending off an ambush in a Viet Nam jungle. In the middle of the firefight, some kind of magic spell had transported them to this Fantasy Land complete with flying dragons, wizards, crazy castles, and dispossessed princes.They would stay trapped here forever unless they could rescue the sorceress Gabrielle. Master magician, Amon, held her captive in his palace; and to reach her, Gil and his men would have to infiltrate Hell itself!

Gil MacDonald, soldier and exile in an alternate reality, must find Yardiff Bey, master wizard and archvillain. Bey has abducted Gil's friend and threatens to destroy this world of mystery and magic that the American has made his home. Coramonde's Prince Springbuck sends him south to the accursed lands of Shardishku-Salama, where Yardiff Bey waits to capture and torture him. With the comet Trailingsword hanging in the sky above, Springbuck sets out with his army to save Gil from an enemy that cannot be slain.
