My faves in each category are in italics, but that doesn't mean I didn't really enjoy most of the books.
Least favourite book: Food and Loathing by Betsy Lerner
Favourite category: Southern - I knew that going in! :-)
Surprising category: Mysteries - I've always thought I wasn't a mystery person, but it turns out there were a lot I wanted to read and I really enjoyed all but one of them.
Least favourite category: Nonfiction - I also knew that going in. But it was good to branch out. And I'd forgotten how much fun humour nonfiction can be, I'll definitely be seeking out more of it to give me some much-needed laughter.
That's it! It was really fun to undertake such a big challenge this year and I'm proud of myself for finishing it.
