Having seen the top reads of 2007 as stated by the SF Site, I feel slightly embarrassed to admit that I've only read two of them - Joe Abercrombie's Before They Are Hanged, which pops up at number 5, and Scott Lynch's Red Seas Under Red Skies. Interestingly, Red Seas Under Red Skies only manages 9th on the list - he was 1st the year before. Either there were a lot of quality books released last year, or fans didn't quite enjoy his second novel as much as the first.
Harry Potter makes the obligatory appearance, along with heavyweights such as Dan Simmons and Steven Erikson. I've heard good things about Simmons' The Terror, and have been meaning to pick it up for a while.
No surprises who is at number 1 - Patrick Rothfuss, with The Name of the Wind. I've got a first edition copy of this novel on my shelf where it has been gathering dust for months. I will get around to it at some point. The hype has matched that which surrounded The Lies of Locke Lamora, so I'm slightly worried it won't meet my expectations. It certainly sounds damned good though.
