Leviathan by Scott Westerfeld has won the Locus Award for best YA book. I did like Leviathan, but, once again, I wish I had more time to read more science fiction so that I knew what else was out there.
Perhaps that's one of the reasons I generally don't get more excited about awards than I do. An award isn't all that meaningful if you don't know the field from which the award winner was plucked.
