Only the hardbacks

Making Money by Terry Pratchett: I love his books, and was very sorry to hear he's got early-onset Alzheimer's. Going Postal and Making Money are both wonderful books, and I look forward to reading more with Moist Lipwig.
Mistral's Kiss and A Lick of Frost by Laurell K. Hamilton: With A Lick of Frost, she managed to write a book where there wasn't any sex until page 160 or so! I'm amazed! And this book actually has an intense, interesting plot (not that the others don't, but the plot is often overwhelmed by the sex). I really enjoyed both of these (almost enough to make me re-read the Anita Blake series, but not quite).
A War of Gifts by Orson Scott Card: This was a short but poignant little story set in the Ender's Game universe. I wasn't going to pick it up, because I haven't liked much of his work since the original quartet, but I did, and it was a nice holiday read.
High Noon by Nora Roberts: This had as much Law and Order feel to it as it did romance. What happens when a police negotiator is stalked (by two different people, nonetheless)? Interesting family situation, personal background, and significant other. I read it quickly and enjoyed it.
