"An Anonymous Girl" – I Liked It a LOT

I finished Greer Hendricks and Sarah Pekkanen's "An Anonymous Girl" for the first time a few months ago, and started reading it again a couple nights ago. I forgot how much I liked this book. I find it quite good – if slightly unbelievable. I do CONSTANTLY forget what the characters are supposed to look like, instead substituting the way I see them while I read.

Sarah Pekkanen has become one of my favorite authors over this last year, and while I've read eight or so books of hers now, this one is currently my favorite.

I will say, the ending kind of fell flat for me. It wasn't BAD, but it wasn't great.

Has anyone else who has read this book liked it a lot?
