An epic battle between good and evil rages as modern-day Grace Archer fights to defend Pandora's Box from Lilith, the one goddess just crazy enough to open it. Can Grace find the strength to protect the box? Can she control her powers before losing her mind?

When the man Grace Archer loves is pulled into the Underworld, she will stop at nothing to get him back. Her quest is complicated by the fallen god Samael, who is on the loose with a dangerous relic that puts all the immortals in jeopardy. With her powers on the fritz, Grace must help track down Samael and retrieve the deadly Eye of Hera before any more gods fall victim to his madness. Daughter of the Greek Goddess Pandora and the Greek God Prometheus, Grace must dig deep to find the power she needs to infiltrate Hades and convince the God of the Dead to release Chris. But when you make a bargain with the devil, you pay with your soul.

Grace Archer has come into her full powers as an immortal and has taken up the mantle offered by her father, Prometheus. Leaving behind everything and everyone she loves, Grace becomes a pawn in a dangerous game that threatens to undo an ancient truce between Gods of Olympus and the Fae. Can Grace find a way to prevent war or will she become the Harbinger predicted by the Gods of Fate?
