I have read a good number of books this year. Most of them have been in Italian, but a few have been in English also. Of those, the following two have stood out:
Paul Leppin, Blaugast. A brilliant little novel. Very decadent. The translation offered by Twisted Spoon press, while not perfect, is very good. Highly recommended.
Georges Rodenbach, The Bells of Bruges: Rodenbach is a very interesting author and Dedalus deserves a lot of credit for putting out this book which is full of the same sort of imagery used by Huysmans, though not firmly in the decadent school. The translation, by Mike Mitchell, is excellent.
