This was the story of Meredith Kercher and Amanda Knox, wasn't it?
It was virtually identical, right down to the picturesque Italian mountainside town, the toxic friendship, the creepy boyfriend.
Don't get me wrong, it was a pretty good story, moved a bit too slowly at times, but still a decent read. But ... this story has already been told. By, like, millions of tabloids over the last decade. I'm not entirely sure it needed to be novelized.
