Everneath

Six months ago, Nikki Beckett vanished into an underworld known as the Everneath. Now she has returned to her old life for six more months, before the Everneath comes to claim her again, this time forever.

Back at home she tries to say goodbye to her family and to Jack, the boyfriend she left behind, while Cole, the immortal who lured her underground, follows her to the surface. He wants her back as his queen, and Nikki has to decide whether to try to cheat her fate or return.

Everneath is the first book in a young adult paranormal romance trilogy that draws on the Persephone myth, with elements of Orpheus and Eurydice.
