Adea was only 8-years-old when the nightmares began, leaving her terrified of the dark. After being disregarded by her own parents, she turns to her older sister, Lyda, desperate for help to stop the dreams. Ready to do anything, Adea could never be prepared for the dark places to which her sister is willing to go to protect her - but as the years go by, and Lyda descends deeper into desolation, Adea fears there may be more to her sister's personal studies than either of them are prepared to live with, and it will haunt them more than any nightmare they can imagine.
