It’s been five weeks, two days, and eight hours since the demons forced Quinn to throw herself into the raging river, since Aaron sacrificed himself to save her, and since his body disappeared without a trace. Everyone wants her to move on, but Quinn can’t, not after his spirit—or something—appears to her at his memorial, convincing her he’s still alive.

When a mysterious box materializes on the very spot where Aaron disappeared, Quinn finds herself at the center of an ancient prophecy of betrayal, revenge, and sacrifice that takes her to the depths of the underworld to face Lilith—Adam’s first wife. If Quinn can stop Lilith from unleashing the demon horde Eve trapped inside the box during the Battle of Eden millennia ago, she will save the human realm and free Aaron from an eternity in torment.

All it will cost her is her own blood.
