Another New Book

I'm taking this directly from the back of this book:

Six months ago, Nikki Beckett vanished into an underworld knows as the Everneath. Now she's returned - to her old life, her family, her boyfriend - for another six months before she leaves again. 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, it it exists.

I really want to read this but know that I already have enough on my nightstand so I am leaving it for you guys to come grab.This is the first in a trilogy based on the retelling of the Persephone myth. It sounds very promising!
