Lilith

Lilith is a fantasy novel by Scottish writer George MacDonald, first published in 1895. It was reprinted in paperback by Ballantine Books as the fifth volume of the Ballantine Adult Fantasy series in September 1969.

Lilith is considered among the darkest of MacDonald's works, and among the most profound. It is a story concerning the nature of life, death, and salvation. In the story, MacDonald mentions a cosmic sleep that heals tortured souls, preceding the salvation of all. MacDonald was a Christian universalist, believing that all will eventually be saved. However, in this story, divine punishment is not taken lightly, and salvation is hard-won.

Mr. Vane, the protagonist of Lilith, owns a library that seems to be haunted by the former librarian, who looks much like a raven from the brief glimpses he catches of the wraith. After finally encountering the supposed ghost, the mysterious Mr. Raven, Vane learns that Raven had known his father
indeed, Vane's father had visited the strange parallel universe from which Raven comes and goes and now resides therein. Vane follows Raven into the world through a mirror (this symbolistic realm is described as "the region of the seven dimensions", a term taken from Jacob Boehme).

Inside the world, Vane learns of a house of beds where the dreamers sleep until the end of the world in death: a good death, in which life is found. Vane's grandfather refused to sleep there and is, instead, forced to do battle with skeletons in a haunted wood. After a treacherous journey through a valley (where the moon is the only thing to keep him safe), Mr. Vane meets the Little Ones, children who never grow up, remaining pure children or becoming selfish and getting bigger and dumber, turning into "bags" or bad giants. After conversing with Lona, the eldest of the children, Mr. Vane decides to help them, and sets off to gather more information, although the Raven (who is also Adam) has warned Mr. Vane that he needs to sleep along with the dreamers before he can really help them.
