Query: Meme Wars

It's the (not-so?) far future and Earth has been transformed into a battleground for viruses of the mind, commonly known as Memes with a capital M. Our hero and his fellow commandos work as mercenaries in the employ of one Meme or another, surfing through life as they struggle to re-create memories periodically lost to them--the price they pay for a secret treatment that gives them eternal youth. Can an all-American boy find love and happiness in a universe where an innocent conversation may leave you infected by a mind virus such as One True, doomed to spend the rest of your existence in its service? Not the tightest or best SF ever written, but a graphic illustration of one possible outcome of meme evolution.--Richard Brodie, author, Virus of the Mind: The New Science of the Meme
