From Titans

The Titans will rise to take their revenge ...

Everyone is searching for Mason.

A glimmer of hope arises when Eris, the goddess of Chaos, sends an invitation to her wedding engagement party. Turns out Mason is the groom and Eris is holding him hostage. At the party, Eris proposes an offer. In exchange for Mason, the descendants must travel to the Land of Reverse and bring back the water King Midas used to wash himself free of his gift.

Further chaos follows when Eris not only sets up a hunt in the Labyrinth of Crete, but makes a bargain with the Titans she rescued. The Titans possess power more than anyone anticipated, and Cronus is hungry for revenge after his own children locked him up in Tartarus. No one is safe. Not even the humans.
