Wow. I love it when a book can take me on that kind of adventure, where a real sense of danger permeates the pages, and I can't tell where things will end up. Palmer is so good that he frequently telegraphs upcoming plot points. A technique which adds another layer of creepiness to the book.
The novel was a delight to read, an alternate, steampunk world in the 20th century, where emerging mechanical men are threatening the magic of the previous generations.
I will certainly be looking forward to other books by this author.
