Everbound

In Brodi Ashton's breathtaking sequel to Everneath-about which New York Times bestselling author Ally Condie said, "Ashton's lovely storytelling and strong-on-her-own-terms main character set this one apart. Wonderful!"-Nikki must travel through the underworld to be reunited with the love of her life. Ever since Nikki Beckett watched as her boyfriend, Jack, sacrificed himself to save her, taking her place in the dark Tunnels of the Everneath for eternity, she's been living a borrowed life.
Desperate for answers, Nikki turns to Cole, the immortal bad boy who wants to make her his queen-and the one person least likely to help. But his heart has been touched by everything about Nikki, and he agrees to help in the only way he can: by taking her to the Everneath himself. Nikki and Cole descend into the Everneath, only to discover that their journey will be more difficult than they'd anticipated-and more deadly.
But Nikki vows to stop at nothing to save Jack-even if it means making an incredible sacrifice of her own. Inspired by the Persephone myth, the captivating first book in this series, Everneath, earned a VOYA Perfect Ten of 2011 and a Whitney Award!
