Man. Wow. 
 Fuck me. 
 I'm still reeling from this one. 
 Okay, personal side note, as an adoptee and a foster/adoptive mom, this one broke me a little. Her story reached me in those tiny crevices of my heart that only a few people know about. Very few books adequately do justice to the stories of children abused in care or how it gets to that point. (The moving homes, etc.) I cried more than once reading her story. Yes, it's that deep. 
 As far as the rest of the story, man. Really this was playing out to not be a romance at all, until love crept in, and then BAM, back to not being a romance, but just a tragedy that is Elizabeth/Nina's life. 
 I can't say more without spoilers so I'll just say- read it. I don't really care if you like dark stories or not. Read it.
