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.
