When sickly orphan Dinah and her best friend trespass in a mysterious mausoleum, the supernatural guardians tell her she must help the troubled souls stored there to pass on peacefully, or suffer a horrible punishment.
Much of the story consists of episodes with different souls in their individual dream realms. Given the centrality of this action I was disappointed that the sub-stories weren't longer and more developed. I would have liked to see more intellectual and emotional challenges for the characters. However, the atmosphere was quite well-done and the book as a whole was an interesting read.
