My Sister, the Serial Killer

I have been going back and forth on whether I feel like this is a 3 or 4, so I'll just go with 3.5 for now, even though I'm not fully convinced on that rating, either.

I have never read a book quite like this. It's utterly unique and twisted and sometimes funny and othertimes sad. I am having a hard time distilling it down to a meaningful review. It's a quick read that I'll remember for a long time.
