This is the second time I've read this book. I liked it the first time I read it and loved it the second time. Shirley Jackson does an amazing job sprinkling clues throughout about the night Merricat's family dies without revealing too much. I had an inkling the first time through, but was never quite sure until the end. Reading through it again makes me appreciate what a good job she did at not giving it away until the end.
I loved Merricat and the relationship she had with her sister. I think Shirley Jackson meant it to come across as a little unhealthy, but I really liked how close they were and how they looked after each other in their own way.
The ending brought up some not so pleasant memories from high school, but I think that just shows how accurately she portrayed the way people behave in mobs and how nasty they can be when there's no one there that will speak up.
