Well, two books. The first is Ray Bradbury's Fahrenheit 451 to brush up for the Jumpstreet event this weekend (you can find details on my website www.jonsprunk.com).
I'm also about halfway through Deadhouse Gates, the second installment of the Malazan series by Steven Erikson.
There's not much I can say about F-451 that hasn't been said a thousands times before. It's both classic and strangely contemporary in its social commentary. If you haven't read it, I highly recommend taking a peek.
So far I'm really enjoying the Malazan series. Erikson delivers a rich, vibrant world simmering with dozens of conflicts major and minor. I've heard some criticism that his novels are difficult to read, but I haven't found that to be the case. Complex and intelligent, yes; difficult, no.
After Gates I will continue with the series (I bought Books 1-6 on a good deal from Amazon).
