The Triune Man — Richard A. Lupoff

Is Buddy Satvan the creator of the cartoon superhero Diamond Sutro? Or is Sutro the creator of Buddy Satvan, the mightiest crusader in the universe? Are these two men, or six? Are they real, or figments of someone's imagination? A challenging journey to the other side of reality that adds up to a triple-play powerhouse of time, telepathy, and extrasensory shock!
