Something strange happens to Joe and Marge on the way to El Paso. They run into Throckmorton P. Ruddygore, a strange wizard who informs them that they are going to die in nineteen minutes and eighteen seconds.
But they also have a choice. They can abandon the current world by taking a ferryboat across the Sea of Dreams to a new life in a new world, full of magic, fairies and wonder.
But along with all its wonders, the new world is also the site of an ancient battle still being fought between the forces of Evil and Good, and the forces of Hell threaten to unleash perpetual darkness.
Joe and Marge not only need their wits to survive in this unpredictable and dangerous world, but must somehow help prevent the oncoming Armageddon.
