Books 14 and 15 are both rereads for me this year. I read The Hobbit as part of the Omnibus 2 secondary book selections, and I'm in the process of rereading the Harry Potter series before the release of the final movie on the 15th which I'm planning to go see in the theatres with DH. (It will be our first movie date in years.) Rather than writing new reviews, I'll just link back to my reviews from last year since I'd write pretty much the same comments again.
