Started re-reading the ASOIAF series. My interest in it had really dwindled in recent years, as waiting so long for Winds to come out.. However, after a few chapters of AGOT, I'm hooked again and already onto Clash of Kings.
There's a very cool reddit where the community is doing a re-read (I think a chapter every two or three days) and are posting discussion - can find here:

I'm obviously playing catch-up, but been very enjoyable to re-learn the theories, etc.
