Challengers of the Unknown #10

Synopsis

In a new city designed of radical new materials, people keep seeing ghosts, so the Challengers investigate. Brenda is skeptical until her dead sister Eileen appears. Brenda finds one tower in the city is made of a NASA alloy that drove astronauts mad. It resonates and gives spirits "quasi-life." Brenda sets up counter-vibrations, with dead Eileen's help, which shake apart the building, catching Brenda in the rubble. When dug out by her friends, she downplays her visions of Eileen as a delusion... as Eileen's ghost sits beside her.
