The Last Missile — David Weaver

A strange recurring dream about a cave draws Jessica back to her birthplace. She discovers the cave is now sealed up. Later, a transparent orb plunges into a hillside and disgorges an occupant who can enter the cave. She discovers she can also enter by ridding herself of all inanimate objects. Inside, she encounters Asef, the person in her dreams. He is from a dimension called Alba. The sphere and its occupant, a tulpa named Jason, are products of Asef's mind. Albans want a nuclear exchange, which will fracture the dimension between the two worlds. Asef uses Jasonââ,¬â"¢s powers to convince the president of his credibility. A renegade Russian general launches a missile at Jason, whom he perceives a threat, but he intercepts it and takes it to the cave.
