The alien’s white curved fangs protruded from his upper jaw. Electric arcs jumped between them. He swung his head down and bit the teen’s shoulder. The victim convulsed as if struck by lightning. To my horror, smoke rose from his scorched hair. Blood geysered from his carotid artery and splattered the brick wall. That could have been me. I wished I could warn everyone. On Earth’s sister planet Hertzia, intelligent life has shed the confinements of the body. That’s because Herzia’s universe exists in the fifth dimension. Although the universes are interrelated, Hertzia’s technology has surpassed Earth’s, with unintended results. Can Earth avoid the same catastrophic future? Emotions remain in Hertzia’s denizens. When they contact humans, can love, kindness, and science defeat ambition, cruelty, and politics? That’s what Patrick O’Donnell, Hertzia’s preeminent physicist, and anthropologist Nichole Danvers, together with Charles Evans, a New York City architect, and Dora Reeves, a TV reporter, must determine. Will love drive one of them to make the ultimate sacrifice?
