by Erich von Däniken (1981)
A spaceport in the Andes! A computer chart in Egyptian ruins! Primitive sculptures of figures wearing space suits! Erich von Däniken's Chariots of the Gods stunned the world with the archaeological discovery that alien beings once colonized earth. Now, in Pathways to the Gods, von Däniken reveals the story of his travels following the trail of the ancient visitors---from the technologically sophisticated stone ruins in the Bolivian Andes to the sensational Sanskrit descriptions of space battles in Calcutta---new proof of von Däniken's startling theory that man descended from the stars!

A teenage girl, naked and badly injured, is discovered by two fishermen in mountain forest in Macabee County, Oregon. Before lapsing into a coma, she asks for someone called Billy, and dies before reaching hospital. The dead girl is identified as Edie Collier, last known to be living on the streets of Portland after quarrelling with her mother. That's how Summer Zeigler, a newly qualified police detective in the Portland Police Bureau gets involved: she arrested Edie for shoplifting six months before. Then the body of Edie's boyfriend, Billy, turns up in the Nevada desert. His manner of death, a wound caused by a crossbow bolt and the removal of his heart and eyes, links him to several other murders. Summer's investigations will lead her to the strange mansion of software millionaire Dirk Merrit, who made his fortune from a computer role-playing game known as Trans. But cyberspace is no longer enough to fulfil Merritt's grotesque fantasies. He wants to play a real-life version of his game. A game with deadly consequences.

Twice before Stephen Fisher has set sail upon the Spiral—that shifting melee of Space and Time that abuts accepted reality at ancient, hidden places. Once he was drawn in by chance, another time by need. Now great and terrible forces older than humankind are calling him back once more. The known world begins to fall apart on the day Stephen is rightfully recognized as head of a giant multinational industry. Magically fortified boundaries have been breached, forbidden thresholds crossed...and demons are descending en masse upon Europe. Malevolent beings from both within the Spiral and without have conspired to spill monsters into the Core—to spread fear and hatred and death...to destroy for the sake of destruction alone. And this unrelenting wave of horrors is but a harbinger of even greater terrors yet to come.
