I enjoyed this just not as much as I was hoping. I think a part of that is that even though I enjoy multiple perspectives and timejumps, in this one when we go back to a time period that we've already seen conversations are repeated and that is one of my biggest book pet peeves.

I was able to predict a part of the ending however the fact that 

Shane was actually her brother and not Paul I did not see coming. Oliver being the killer wasn't shocking though. I figured he ended up dead for a reason
