Sense and Sensibility by Jane Austen, of course. A re-read, obviously, but I'll list those anyway.
Billions and Billions: Thoughts on Life and Death at the Brink of the Millennium by Carl Sagan. Kind of a popular science/philosophy book written when Sagan was battling his final illness. Not bad, but I prefer Dawkins for that sort of thing.
The Crimson Petal and the White by Michel Faber. I'm not gonna lie, I only read this because I saw that Gillian Anderson was going to be in a BBC adaptation. Kind of a depressing book, actually.
A Brief History of Time by Stephen Hawking. Because who doesn't want to be rocking with Hawking? Some of the stuff is out of date, but it's good context for the current ideas.
Lady Chatterly's Lover by D. H. Lawrence. Interesting for historical context, but complete fail in philosophy of sexytimes.
Fledgling by Octavia Butler. I think this book may have been written in response to Twilight. It's another take on vampires, but it has an actual heroine and no one is emo.
Wyrd Sisters by Terry Pratchett. Hehehe, these books are fun.
Mort by Terry Pratchett. A re-read, prompted by reading Wyrd Sisters.
The Girl Who Kicked a Hornet's Nest by Stieg Larssen (check title and spelling for accuracy later). I thought the first two were decent reads, but then I found out they were leading up to this one, and now I like the entire series better.
Infidel by Ayaan Hirsi Ali. About becoming an atheist after a fairly strict Muslim upbringing. Pretty interesting.
Careless In Red by Elizabeth George. British psychological mystery, not so much thriller. It was passable, but I don't think I'll look for more of these books.
Animal Dreams by Barbara Kingsolver. Yet another re-read, because I quite like Barbara Kingsolver. Her books have a bio nerd undercurrent.
Morgan's Run by Colleen McCullough. Historical fiction dealing with the transportation of British convicts to Australia. Apparently, fairly accurate.
The Strategic Teacher: Selecting the Right Research-Based Strategy for Every Lesson by Harvey Silver, Richard Strong, and Matthew Perini. Guess what I'm studying.
A Night Too Dark by Dana Stabenow. I'm not sure whether Stabenow has let her character stray too far into Mary Sue territory or not. Cornwell sure as hell did.
Prodigal Summer by Barbara Kingsolver. Reread. See above.
A Stranger in the Family by Robert Barnard. This book is billed as a suspense novel, but it's not suspenseful at all. It's a decently written mystery, but all I got from it was a vague sense of curiosity at how it would turn out.
Stones in the River by Ursula Hegi. Reread, about a young woman in Germany before and during World War II. Very good.
The Ancestor's Tale by Richard Dawkins. I needed a book to take to work with me, so I read this again. And then got stuck on it for the rest of March, because I was doing homework most of the time.
The Hunger Games by Suzanne Collins. A certain sister has been bugging me to read this. Pretty good, have to read the rest now.
American Gods by Neil Gaiman. A reread.
How to Be an Effective Teacher by Harry Wong. He makes some good points, but he's also kind of annoying.
Beyond Discipline by Alfie Kohn. This book appeals to my inner hippie.
Tooth and Claw by Jo Walton. Another reread, because this book is a delightfully wacky take on the classic Victorian novel.
The Chrestomanci Chronicles, Volume I and II by Diana Wynne Jones. A reread in honor of the author.
Pyramids, by Terry Pratchett. Working my way through Discworld. Hilarious.
The Red Queen by Philippa Gregory. Her historical fiction is pretty entertaining, and I had to read the counterpart to the White Queen. The Red Queen of the book is a v. obnoxious person, but makes for a good story.
I was freaking out about schoolwork, so may not be a complete list.
The Lacuna by Barbara Kingsolver. A bit different than a lot of her other books, but pretty interesting historical fiction. Funnily enough, a book with political undertones in a story about a writer with political undertones in his books.
