While Olympus trembles, Sleep awakens.

The pantheon is under attack. Earthquakes rip through Gaia. Ancient monsters rise from the Titan Pit. And Zeus demands loyalty at any cost.

When Hypnos offers the king of the gods a dangerous bargain—he will uncover the source of the attacks in exchange for one immortal child with Jen—he sets forces in motion that could fracture Olympus forever.

But Jen has her own mission.

As goddess of abused children, she uncovers a horrifying mortal crisis in West Africa—one that pushes her to strike a risky alliance with Scylla, the sea monster no one trusts.

Separated by war, secrets, and divine politics, Hypnos and Jen must decide what kind of gods they will become.

Because love may have made them powerful.

But independence will test them.

In this gripping seventh installment of The Underworld Saga, loyalty is strained, monsters rise, and even Sleep must confront the cost of ambition.
