I picked this up when I was in Montreal. It was written in French and was up for the Gov. General's Award. I can see why.
The back of the English edition makes it sound like a quasi, if not full on, murder mystery. This is not really the case. The terror in a small town does have to do with a few murders, though the killer is not a mystery for long. But the terror is just the murder, it is also the treatment of people who are different from the majority in a small town. This is true of the two central characters.
The description of the town as well as the description of scent is wonderful. The writing shines more than the plot.
