A few thoughts:
Carl Hiassen's thrillers are definitely part of the Florida soundtrack, while Chabon's Summerland is a uniquely American fantasy. Mark Van Name's first novel is an interesting take on the boy and his dog style of tale (and very much in the Pip and Flinx mode, with the main character hiding his enhancements from the rest of the universe). Dzur is Vlad having a very good dinner, along with what happens when you're tasked with killing your god and still have to save your ex-wife from your mistakes. Meanwhile, Steele's A King of Infinite Space wraps up the Clarke County saga with a tip of the hat to his next major project. Karen Traviss's Wess'har novels wrap up nicely with Ally and Judge, and I ended up finding the story of Eddie Michallat the glue that held the series together. Brown's Helix was disappointing (and very 1970s British SF at heart).
Total read so far in 2008: 64 books (not counting uncatalogued rereads)
