Well, I just finished Gene Wolfe's "Book of the New Sun" with the final volume "Citadel of the Autarch." The story is good, there are wonderful images and the prose is flawless. It's also frustrating. It's the kind of book you can't read once and understand fully. It requires that you go back and look again. The narrator basically says that at the end of "Citadel of the Autarch":
"Have I told you all I promised? I am aware that at various places in my narrative I have pledged that this or that should be made clear in the knitting up of the story. I remember them all, I am sure, but then I remember so much else. Before you assume that I have cheated you, read again, as I will write again."
And I will do just that, but it will have to wait. I have so many books stacked up waiting for me, I have little time to reread. (Which is something I'm starting to change.) I moved right onto the next book.
That book is "The Extinction Club" by Robert Twigger. Here's a review of the book. They pretty much don't like it and for good reasons. However, when I started the book I approached it differently and that may make all the difference. I'll tell you more when I come out the other end.
