I haven't yet read the book, and do not know much about it. Here is the description of the book from the publisher.
"Virtually Forever is a love story with an unusual twist. Michael Stanton has an obsessive interest in the long-dead, hauntingly beautiful silent screen actor, Louise Brooks. Involved in an military program to replicate world leaders in a virtual reality domain, he clandestinely uses this technology to recreate the Jazz Age world of Louise Brooks. Entering it, he appears as a wealthy and mysterious stranger and, soon after meeting Louise, a love affair follows against the backdrop of Hollywood parties and studio politics. Back in the real world, Michael’s colleagues have discovered that there is an unknown intruder in their top-secret computer system. The plot weaves between Michael's tempestuous love affair with Louise and his desperate struggle to safeguard her and her world from annihilation — at any cost."
