Hypnos goes to Mount Olympus to offer Zeus a deal. He'll make it his mission to find out the source of the recent attacks on Gaia--horrible earthquakes that have already released one monster from the Titan Pit--if Zeus will agree to let him and Jen have one immortal child. But this new quest just might get Hypnos swallowed and trapped for all eternity.
When Zeus learns of Apollo's vision--of Than's twins finding Prometheus, Zeus's number one enemy--the hunt for Prometheus begins. Zeus and his allies want to bind Prometheus and kill the twins before their threat of a revolution becomes a possibility. If Hermie and Hestie don't find the Titan first, they have no chance of fulfilling their destiny or of surviving Zeus's threat against them.
The rebellion led by Hades prepares to storm Mount Olympus, but their every move is sabotaged. Morpheus is torn between his allegiance to his Underworld family and the oath he swore to Zeus under duress. Forced to play both sides, Morpheus sees no hope for the rebellion. As the gods square off, how can one identify the friend from the foe?
