What were your absolute *least* favorite reads this year?

Thanks to all who contributed their favorites in my last post about your favorite reads this year. Now let's invert the paradigm: what did you hate this year? What did you finish begrudgingly, slog your way through, or hit the eject button and DNF because it was so awful? For me, my least favorite this year was Blood Test by Charles Baxter. It's barely scifi, but for a novel that says "A Comedy" on the cover... it's not funny, even once, even a little bit. It's almost like an expanded, excruciatingly boring story from the Machine of Death anthology. Awful.

What were your slogs, and why?
