Although it's not a book, the Linux documentation [1] is actually very good and does the job of explaining design and architecture of the kernel. I'd also suggest reading "Unix Internals" by Uresh Vahalia. While this book is from 1995 and it doesn't cover Linux specifically, it's an exceptional resource for understanding how *nix kernels work in general.
