First, I agree with the author that this is not a horror novel. Yet it certainly is a "dark" brand of fiction. I am sure it stands alone well, but it also takes a good deal of the cast and settings from Ms. Kiernan's earlier works. Those familiar with her work will have noticed a tendency to be more "accessible" in recent novels. The very good news of this new book is that she manages this without losing anything of her amazing use of language and literature or serious twisting of characters already known to us. Her telling has become a lot "clearer" in the sense that more issues are explained and/ or resolved. While it has been said about her earlier works that her characters in the dark struggle for the light, the reader can now actually see that there is a light - somewhere. However, the dark, the mysterious, and the brutal tones of her vision have remained. Still, if you are into clinical, graphic descriptions of gruesome bloodshed, explosions etc., you are wrong here despite a good deal of these processes going on. In addition to the developments mentioned, she also took on the challenge of writing a large proportion of a rather adult book from a child's perspective, holding the tension in two narrative threads for a good part of it and delivering a plot with numerous twists and turns (turnarounds, really). And she comes out the winner.
Although different from previous works, long-time fans will enjoy it and newcomers will suddenly wake to her rich and strange dreams. It makes an excellent starting point to travel them.
