I've heard such great things about this book, so I decided to bump it up my list, and I'm glad I did! 
I don't think I've ever quite read something like this before, and although it was a bit different then what i was expecting it enjoyed it and I loved the different POVs from Ansel counting down his final hours to hearing from those who had know him, and I loved the fact that this was indirectly such as his sister in law rather than his wife! 
This book definitely makes you think about nature vs. nurture, and I found myself feeling sympathy for Ansel at times and then absolutely despising him at others as his. Although his past could be the reason he did what he did, it wasn't an excuse! Wow, that's quite deep for a book review! I did guess a few of the twists, but I really enjoyed this book and will definitely be recommending it!
