The main protagonist is a very irritating person. She seems to have no mind of her own, and,  even worse, the author seemed to think that that was a good thing. The other characters are a bit unlikeable as well. 
The plot was not so brilliant and in parts downright unbelievable.  Someone finds a  body whilst walking a dog and then no one else does for quite some time, despite the flies and the smell.
There was one redeeming element and that was the nature descriptions,  which were  nicely done. I enjoyed those bits.
But on the whole, not an enjoyable book, I was happy to get to the end.
