Carl Prescott may have saved the world from the Beast, but the duties of the Invisible Hand never end. The story begins when a medieval castle is discovered underneath the Throndike Institution. While the professors search for clues, our hero is summoned to Hell to meet the demon Sylvia. She once ruled a satanic kingdom in Eastern Europe from that castle, and will do so again.

There is much more to this beautiful woman than evil intentions. To stop her plan, Carl must first understand why she is so focused on him. To learn the truth, he must face God, Satan, and Death. In this nonstop action-packed adventure, he must stand at the Crossroads of Existence and cross the Rope Bridge to meet his destiny.

If he succeeds, life can return to normal. If not, the galaxy and every sould therein will be devoured by a voracious black hole, which even God will be powerless to stop.
