I could not put this book down. It was such an interesting story for most of the book and I found myself thinking about it during the day when I couldn't read it.

The alternating viewpoints gave the alternating plotlines - a woman searching for her lost sister and a woman searching for herself. The feelings that each woman has for the other showed the intricacies of sisterhood in a genuine way. They love each other, are jealous of each other and don't fully know the other as well as they thought. Kwok did well here.

The story had many loose and messy ends and I felt let down by some of them. Kwok gave us a suspenseful mystery, created plenty of potential suspects, but left too many threads untied. The end of the mystery felt rushed and out of sorts with the preceding 80% of the book.

I had a hard time believing Lukas never noticed Sylvie's birthmark before or that he was willing to continue their romantic path so soon after understanding the truth. I wanted to know more about why he immediately felt so strongly about her after not seeing her for 25 years and was seemingly OK with the revelation of who they are to each other.

Filip was an odd character to include against Lukas. Did Lukas forget what Filip revealed in high school? Was he embarrassed and that is why he became angry with Filip so often and quickly? This storyline could have been expanded in an intriguing way.

Ma's chapters didn't seem that relevant to me until the end. I felt blindsided by her truths at the end. I'm not sure if I missed some dropped clues in earlier chapters but I felt her secrets tumbled out as a way for Kwok to tie up open points in one swoop.
