John Carpenter's Tales of Science Fiction: The Envoy (John Carpenter's Tales of Science Fiction: The Envoy #2)

Alien contact? Or ghost invasion? Or perhaps... both? Intruders or visitors? Invaders or benefactors? Scientist Ben Raines seeks to contact the spirit of his dead wife, but finds an entirely new romantic attraction. His old college buddy Steven Allard has spent millions to make contact with an alien consciousness... but does it wish to help, or harm?
