Drake's Treasure is Robert Stupack's first book, although he has a number of other projects in mind. He has recently completed the preliminary evidence-gathering phase for a second work, tentatively entitled, "The God of San Quentin". Mr. Stupack investigates the evidence indicating that the first inhabited of California worshipped and made human sacrifices to a "God" that lived at the fiery center of a geothermal volcano on the grounds of today's San Quentin Prison. .
