Isle of the Dead
by Roger Zelazny
Sandow is jolted from his wealthy, indolent lifestyle by a series of messages, each accompanied by a picture of one of a number of people once important to him, and all dead for many years. Sandow realizes the pictures could be fake, and he has other obligations, one of which is responding to a call for help from a friend, Ruth Laris. In the course of investigating her disappearance, he receives another message that he will find all his friends "on the Isle of the Dead". The message is in Pei'an, addressed to Shimbo (the name of the Pei'an god connected with Sandow) and signed by Belion (Shimbo's traditional enemy in Pei'an mythology).
Sandow soon learns that somebody has been stealing the memory records and tissue samples of people who died on Earth. These things are required of everyone who lives on Earth, so they can be recalled to life should the need arise. The six missing sets are of the people whose photos Sandow received.
Visiting his Pei'an mentor Marling, who is dying, Sandow learns that his tormentor is Gringrin, another Pei'an who was denied communion with a deity despite passing almost all the tests. Gringrin vowed revenge on the other worldscapers, starting with Sandow. Somehow Gringrin has been able to unite himself with Belion.
Sandow helps his mentor end his life with the glitten root ceremony, in which two telepaths take the hallucinogenic root and have a shared dream, from which only one returns alive. This is also used for duelling between telepaths, which is what Sandow must do when he finds Gringrin. After the funeral, Sandow sets out for Illyria, the world he made which has the Isle of the Dead.
Landing by stealth, and armed to the teeth, he sets out to walk the remaining distance to the Isle of the Dead. He now believes that Gringrin intended him to be lured there, and slowly humiliated before all the people who ever mattered to him. He is sure Gringrin has made a major mistake by staging this on a world Sandow made. All the forces on the planet will be allied with Sandow; he is the world's God.
He comes upon Gringrin himself, alive but injured. Things have gone badly wrong. One of the recalled persons is Mike Shandon, a con man who is also a telepath, and a deadly enemy of Sandow's. He has persuaded the god Belion to abandon Gringrin and go to him. Apparently the Pei'an gods are real and Gringrin, attempting to ordain himself independently, asked for a creative spirit to come to him, but instead was chosen by Belion. Now, Belion's abandoned him and gone to Shandon. Gringrin wants to flee, but Sandow is determined to rescue as many of his friends as possible.
As the two cross the river to the island they meet more of Sandow's revived enemies and friends. From one of them, a feisty dwarf named Nick, Sandow learns that his recalled wife Kathy is having an affair with Shandon.
Sandow decides to buy Shandon off, which he is well equipped to do. As the two negotiate and link minds to confirm the deal, the gods assert themselves and a battle begins in which Shimbo's air and water battle Belion's earth and fire. A storm rages as the ground shakes and splits. Both Sandow and Shandon are consumed by their godgame, until Sandow sees Nick try to help Kathy, only to fall with her into a fissure. Both die, and at the same moment Shimbo deserts him. Shandon/Belion continues attacking, and Sandow goes down under a pile of rocks, breaking his leg. Sandow has one last trick - a laser weapon surgically implanted in his middle finger. In a supremely ironic gesture, he "gives Shandon the finger", killing him and ending the battle.
Sandow crawls away to find a "power-pull" energy nexus, so he can use its energies to summon his orbiting ship. On the way he encounters his last revived friend/enemy, Lady Karle, alive but entombed in a cave. She and Sandow were lovers who were torn apart when a corporate war, in which Sandow was a player, ruined her family and drove her to seek revenge on him. Sandow bitterly dismisses her cries and goes on. He meets Gringrin, mortally wounded. Gringrin begs him to perform the glitten rite with him, using the location of the recall tapes as an incentive. Once in the rite, Gringrin confesses that the recall tapes were ruined by Shandon's conflagration, but Ruth is alive in a hospital and can be saved. In the psychedelic trance, Sandow faces Death in the shape of the Valley of Shadows. He sees all the worlds he has made, and realizes that as long as he can create life, casting worlds like "jewels in the darkness", he has a purpose. Gringrin in turn loses his dread of death, and walks happily into the Valley.
Waking, Sandow crawls on and reunites with his ship, then returns to Lady Karle's cave with a weapon and vaporizes the rock. They hobble to the ship together.
