Professor Morse Brulay is writing to us from his jail cell in Ecuador. Brulay is a roamer and a seeker of the mysterious, the new, the erotic - but also of enduring wisdom. In his search for the Deep Code - the secret of time travel - he runs afoul of the Fomors, the dark spirits of the Druidic world. Cursed with terrifying flashbacks to his prehistoric past, Morse loses his moral bearings and flees to the Amazon jungle in search of spiritual rebirth. There among the Indians he finds the knowledge he seeks and is joined in his new vision by Lotte, the beautiful biologist.

In their effort to protect and nourish this knowledge, Morse and Lotte now find their own lives in danger. Only the power of the discovered wisdom will determine what happens to them, and to the wisdom itself.
