My "reading theme" this year is fantasy.
At the moment, I'm (re)reading The Sword of Shannara, which is the first high fantasy novel I ever read, back when I was younger than The Lad is now. Because it was the first high fantasy novel I ever read, I didn't say then (as I'm saying to myself now) "Holy Carp, this thing's starting as a shameless ripoff of the plot of first few chapters of The Fellowship of the Ring!!!" Nevertheless, it's pleasantly readable, Tolkien doesn't own the bits and pieces of a classic medievalesque fantasy so I'm more amused than annoyed, and since Brooks managed to knock out 30-ish books in this series he must, at some point, have found something original to say with those bits and pieces. So I'm in (at least for a while).
Speaking of being amused, I started the year with the first (and my first) Discworld novel, The Color of Magic. Looking forward to more of those.
Between Brooks and Pratchett, I could probably just call it "The Year of the Terrys", but I've set aside a ton of other things I want to sample this year (including several recommendations from The Lad. Unless I wear out, this could turn into a 2-year project.
