Last spring, Nikki Beckett vanished, sucked into an underworld known as the Everneath, where immortals feed on the emotions of despairing humans. Now she's returned—to her old life, her family, her boyfriend—before she's banished back to the underworld . . . this time forever. She has six months before the Everneath comes to claim her, six months for good-byes she can't find the words for, six months to find redemption, if it exists.

Nikki longs to spend these months reconnecting with her boyfriend, Jack, the person most devastated by her disappearance—and the one person she loves more than anything. But there's a problem: Cole, the smoldering immortal who enticed her to the Everneath, has followed Nikki to the mortal world. And he'll do whatever it takes to bring her back, this time as his queen.
