Buying Myself a Birthday Present

Jonathan Strange & Mr. Norrell is in my purse for the flight home this evening--you guys have been talking it at me, and I listened.  But this trip may involve a swing by one of the good bookstores in Harvard Square, so what should I get myself?  Music recommendations welcome too.  I trust y'all to steer me right.  Or if there's something you are considering, but aren't sure you want to read/watch/buy, draft me, and I'll do some custom reviews.
