The Eyre Affair (Thursday Next, #1)
An enjoyable romp through an alternate universe, Jane Eyre, and time, featuring dodos, literary detectives, and a man called Jack Schitt. A jolly good time, if you're okay with suspending disbelief and don't mind nefarious supervillains. Am most definitely looking forward to reading the next books in the series. (I picked this one up and then accidentally read it half way through in one sitting.)
A warning: this book is not for people who insist on being pretentious jackholes. I hope you know who you are, and you don't deserve to have fun anyway.
