Terrified for Nikki's survival, Nikki and Jack begin a desperate attempt to reverse the process through any means they can think of. Even Cole, who they expected to fight them at every turn, has become an unlikely ally—but how long can it last? Nikki needs to feed on Cole to survive; Cole needs Nikki to gain the throne in the Everneath; Jack needs Nikki because she is everything to him—and together they must travel back to the Underworld to undo Nikki's fate and make her mortal once more. But the Queen has not forgotten Nikki's treachery, and she wants her destroyed for good. Will Nikki be forced to spend eternity in the Underworld—or can she bring down the Everneath once and for all?

In this stunning conclusion to the Everneath trilogy, Brodi Ashton evokes the resiliency of the human spirit and the indomitable power of true love.
