I read a bunch of Terry Pratchett's Discworld novels this summer, not really in order though. It's just a wonderful series, funny, but a coherent enough fantasy world that you care about the stories and the characters. I wish I'd had these to read when I was a kid.
Also been reading John Scalzi's novels lately. He's a fairly "lite-science" science fiction writer and pretty efficient at telling a tale (things happen! characters move!). They're good reads and the 3 part "Old Man's War" series is good fun. I'm in the middle of reading Zoe's Tale, which is a re-telling (so far) of parts of the "Old Man's War" series but from the perspective of Zoe, who while a central character in the series never dominated the perspective of the original books. This one is entirely from her point of view, which as a teenager, is much different that the adults around her. Here's an interesting video of a conversation between Cory Doctorow and John Scalzi which covers in part Zoe's Tale.
