Near the ancient Temple of Apollo, young idealists protest at a European governmental conference. Inside, business lobbyists mingle with lawmakers, seeking profit and influence. Then the charismatic leader of the protest goes missing. 

The next day a body is discovered, placed like an offering to the gods. One day later a recent, broken corpse is found at the foot of the cliffs from where blasphemers were once tossed to their deaths. 

As a storm closes in and strange lights are seen on the mountain, power at the conference centre is cut off and all are isolated. No one trusts anyone else. Is a killer stalking the corridors? Or are primal forces reaching out from the past? 

Like the cryptic Oracle of Delphi, Cassandra Fortune must supply the answer before the conference is over. And before more die.
