The second siege

Powerful forces are gathering to claim the Book of Thoth, an ancient artifact holding the key to creation and destruction. Max McDaniels and David Menlo, guided by Rowan's top agent Cooper, must protect this book from the demon Astaroth, whose release has already made the world outside Rowan's gates a dangerous place. Cut off behind enemy lines, Max and his allies journey across Europe, through the fabled Frankfurt Workshop and the Black Forest, and even beyond the veils of their own world.
