Valis (1978) by Philip K. Dick. I'm gonna read the Valis trilogy...Valis is book one and presents PKD's Exegesis along with the novel of Phil and his double Horselover Fat. At one point of the story there is five Phil's talking....Phil, Horselover Fat, Phil from the past, and two Phil's from the future! LOL Pretty heavy sci-fi....the next two books are The Divine Invasion (1980), and The Transmigration of Timothy Archer (1982). 3.5 outta 5.0.
