Realtime Interrupt

Description

From back cover Bantam paperback January 1996:

When Joe Corrigan awakens in a Pittsburgh hospital, he discovers that his life no longer exists. As director of the supersecret Oz Project, he volunteered himself as one of the first human inhabitants of a computerized virtual world indistinguishable from reality. But the Oz Project failed, and Joe has lost everything: his wife, his friends, his colleagues, hist past. Now he finds himself in an unfamiliar world where nothing is quite as it should be. Only Lilly, a fellow Oz volunteer, is different from the others-- somehow more *real*. Together, they learn the terrifying truth about the world they inhabit. But can they discover a way to get out alive?
