I just stumbled across these necklaces on etsy and LOVE them.  They are perfect for that book lover in your life - you know who I'm talking about.  The person who reads the novel before it's made into a movie, who buys both the e-book and physical version of a book, who spends way too much at amazon.com and has books spilling out of bookcases, kitchen cabinets and overflowing off of end tables and counter tops... happy shopping!

My personal favourite - a la Game of Thrones
For the mischievous HP fan
And my most favourite Tolkien quote
