Valis by Philip K. Dick

Trade paperback format. 

The first book in Philip K. Dick's final trilogy (followed by The Divine Invasion and The Transmigration of Timothy Archer), VALIS encapsulates many of the themes that Dick was obsessed with over the course of his career. A disorienting and bleakly funny novel, VALIS (which stands for Vast Active Living Intelligence System) is about a schizophrenic man named Horselover Fat (who just might also be known as Philip Dick); the hidden mysteries of Gnostic Christianity; and reality as revealed through a pink laser. VALIS is a theological detective story, in which God is both a missing person and the perpetrator of the ultimate crime.

Taking place in the same universe as Dick's Exegesis, VALIS is a dense novel, but one that is absolutely essential to understanding the author's off-kilter worldview. Much like Dick himself, the reader is left wondering what is real, what is fiction, and what the price is for divine inspiration.
