This 2006 mystery, set firmly in the tradition of Gothic greats like Jane Eyre, kept me guessing from start to finish. The premise is intriguing (and you may find yourself a little bit envious of the narrator's bookish existence). A little dark and deliciously creepy, perfect for curling up with on a cold winter's day. Take note: a few unsettling scenes if you're a sensitive sort. (I am.)
