"They were never meant to live. Now the multiverse bleeds because they do."

Ariel, Jenna, and Iris were supposed to die on Flight TE901?claimed by the Underworld, broken in body and soul, returned to Persephone's cold embrace. But they defied death... and she never forgets her debtors.

Now trapped in a cosmic game overseen by the death goddess Ereshkigal, the trio is cast into alternate realities where survival is not guaranteed?and success is never simple. In one such world, a crippled scout ship crashes on a hostile planet overrun by monstrous blood drinkers. With its crew on the edge of annihilation, and a lone scavenger girl as their only guide, the three must choose: intervene and risk exposure?or walk away and preserve their souls.

But Persephone is watching. Hunting. Waiting.

As swords of Tartarus clash with swarms of alien horrors and ancient hunger rises from beneath the earth, the line between gods and mortals blurs?and the cost of defiance is written in blood.

Part myth. Part machine. Part nightmare. This is not a simulation. This is survival.
