It's the Hollywood of the future, where moviemaking's been computerized and live-action films are a thing of the past. It's a Hollywood where Humphrey Bogart and Marilyn Monroe are starring together in A Star Is Born, and if you don't like the ending, you can change it with the stroke of a key.
A Hollywood of warmbodies and sim-sex, of drugs and special effects, where anything is possible. Except for what one starry-eyed young woman wants to do: dance in the movies. It's an impossible dream, but Alis is not willing to give up. With a little magic and a lot of luck, she just might get her happy ending after all.
From the Paperback edition.
In the Hollywood of the future there's no need for actors since any star can be digitally recreated and inserted into any movie. Yet young Alis wants to dance on the silver screen. Tom tries to dissuade her, but he fears she will pursue her dream--and likely fall victim to Hollywood's seamy underside, which is all to eager to swallow up naive actresses. Then Tom begins to find Alis in the old musicals he remakes, and he has to ask himself just where the line stands between reality and the movies.
