Your shadow half remains
(Book)

"Riley has not seen a single human face in longer than she can reckon. No faces, no eyes. Not if you want to survive. But when a new neighbor moves in down the road, Riley’s overwhelming need for human contact makes her throw caution to the wind. Somehow, in this world where other people can mean a gruesome, bloody death, Ellis makes her feel safe. As they grow closer, Riley’s grip on reality begins to slip and she can no longer fight her deepest desires. All Riley wants to do is look."--,Amazon.com.
