My biggest issue with this book was the storytelling. So much of the narrative is told through conversations. Cass mysteriously shows up on her mother's doorstep three years after going missing, and then the majority of the rest of the book is her interviews with FBI agents. Everything we hear about her trauma is through dialogue. It makes for a very boring story. I don't want to hear people talk about the things that happened, I want to see the events themselves. Even if it's told through flashbacks or memories. Anything is better than dialogue.

I understand why it was chosen for this story, but I think that choice was incredibly detrimental to the book.

Apart from that, it was pretty fine. Just another thriller that to be perfectly honest, I won't be thinking about again. The characters were fine. You can basically guess the ending from the first chapter. But it was still compelling enough that I wanted all the answers. Glad I read it for the answers, but I don't think this is one you'd be missing if you gave it a pass.
