Jack McDevitt is a former naval officer, taxi driver, English teacher, customs officer, and motivational trainer, and is now a full-time writer.

Chosen as One of the Five Best SF Novels of the Year by Library Journal.

The beginning and end of Cauldron are beautifully linked, illuminating both the journey that lies within the novel and the compulsion of human beings to explore the boundaries of their environment, be it a continent, a world or outer space. Anyone pessimistic about our own space program might take heart in reading Cauldron.
