VALIS is the first book in Philip K. Dick's incomparable final trio of novels (the others being The Divine Invasion and The Transmigration of Timothy Archer). This disorienting and bleakly funny work is about a schizophrenic hero named Horselover Fat; 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.
