I recently picked up the latest Wednesday Next novel, but I haven't finished it. I read the previous three in pretty quick succession a couple of years ago, and while they were amusing and very compulsive reading, they also offered pretty quickly diminishing returns. It's a cute conceit that he's following in those books, but it's essentially four (so far) novels from one joke. Still, they're good to read when I need some decompression time from the "heavier" stuff I normally read.
