It took awhile, but I've finally finished my Hugo reading list for the year with Michael Flynn's Eifelheim. Of this year's crop of nominees, this was by far the best written of the lot. Flynn is a very gifted writer, with an unbelievable grasp of European history (I had the pleasure of hearing him speak on the subject 2 years ago).
However, I'm still leaning towards Blindsight for my non-existent Hugo vote this year. In a year packed with so many big ideas books that are actually well written to boot, Eifelheim just feels a bit underwhelming.
