Nothing, however, prepares her for the burden of having to raising a child in confinement. Out of fear, she pushes aside the truth about a world her son may never see for a myth that just might give meaning to his life underground. But when fate intervenes, Blythe and her son manage to re-emerge, only to find themselves in a world even more terrifying than the one they left behind.
