A short and likable novel that does several neat things but ultimately does not rise to greatness. The first thing you notice about it is the cover art, which is just about perfect. The next thing is that the story is a re-interpretation and re-exploration of Lovecraft's _The Dream Quest of Unknown Kadath_. It is a sort of Beowulf/Grendel situation. This time the a story is based on the outlook and experiences of one of the natives of the Dream as she ventures across her world, seeking a woman who has traveled to the waking world. I liked these parts of exploration and travel, as the author fills in tons of tiny and more quotidian details to HP's antediluvian world. More generally, I just like these types of stories and enjoy these fan-fiction type efforts to explore/expand/re-imagine earlier works from different view points.
So! That is the meat of the book, and it is good. The negatives are that Dream Quest of Unknown Kadath was never my favorite HP work; and I wish she had re-interpreted one of his stories that I am less luke-warm about. Also, the ending is perhaps not perfect, and just kind of pleasantly fades out. And finally, I thought that there was a bit too much beating of the cyclopean, undead horse of HP's sexism. A little kicking would have been fine, but the sustained drubbing it receives isn't really why I read novels.
