Ana was the strongest part of the story for me, she's been berated and so unloved her whole life that it broke my heart within the first pages. Her mother felt more like one of those wicked stepmothers in fairy tales to me because of the lack of maternal instinct. I still can't wrap my mind around that Li was her biological mother. I just wanted to hug Ana and assure her she is a great person and worth living for. The isolation Ana felt is so immense, she is literally alone and new in her world because everyone else has been living forever and known each other. Can you imagine that crippling loneliness with the ostracization from society on top of that? I enjoyed seeing her progression from being suspicious and guarded (with good reason!) to be more open and sure of herself. Much of that can be attributed to Sam, which I really appreciate him for. I'm still not sure why he was so nice to her (like Ana, I was suspicious but no ulterior motives were revealed so it can be assumed he's just really a Good Person) but he gave her what she never had: love.
I'm interested to see where this series takes off because I think it's a pretty good start. The characters and the settings are set up in this so I hope to see more of the plot and questions explored in the next one. Incarnate is a book that I think is worth trying out!
