Hades's Promise

The gods are at war. And Therese is running out of time.

With Olympus divided and Zeus’s authority cracking, a new threat rises from the depths. Poseidon’s trident has been stolen. Amphitrite has vanished. Ancient enemies gather their strength.

And Therese is days away from giving birth.

As prophecy tightens its grip around her unborn twins—children destined to restore faith in Mount Olympus—Therese must navigate betrayal, shifting alliances, and a battlefield that spans heaven, earth, and the Underworld.

Thanatos will do anything to protect his family.

But even Death cannot stand between his children and destiny.

When the final clash erupts, Therese must decide what kind of goddess—and mother—she is willing to become.

In this explosive sixth installment of The Underworld Saga, love, war, and prophecy collide in a battle that will redefine Olympus forever.
