What I enjoyed about this book is that the ending caught me off guard. For some reason,as I was reading I thought this book was a love story and so I expected the ending to be a happy one. But when I read the ending- both of them, I realized that this wasn't a love story at all. This was a story about a man breaking free from conventions and finding his own way. This book was about his evolution.The woman is just a catalyst. I read it and got to the "first ending" and being lulled into complacency by the promise of a happy ending, I thought it was a good one. Then I turned the page and read the "second ending" and I was disturbed. After I digested the shock of it, I realized that the happy ending was the second ending.She had helped him break free from the shackles of convention- and it cost him, but in the end he broke free from her and her duplicity- he would find his own way now.
