A lot of my reading this year was comic books. This was the first full year I've spent following comics for some time, and it was great to discover how many good writers there are out there.
Anyway, the books I particularly enjoyed and found well written this year were:
Red Hood & the Outlaws
All New X Men
Astonishing X Men
X Men: Legacy
Avengers vs X-Men
Wolverine & the X-Men
As you can tell, I have become a bit of an X-Men fan. I also really enjoyed reading some of the collections of seventies Chris Claremont written X Men. I intend to read more of those this coming year.
