The Cucukoo's Calling book by Robert Galbraith aka JK Rowling. It was awesome to open this because 1) It was a complete mystery 2) I enjoy Rowling's style and am anxious to see it applied to an area outside the Harry Potter series 3) I didn't know that she had a new book out and 4) I 'hibernate' in winter by reading tons of books. Overall it was an excellent gift for me!
