🛑 ‼️🚨I do want to say that this book should have had trigger warnings for sexual abuse of children, self harm, thoughts and actions of suicide, and a pretty graphic scene of death. 🛑 ‼️🚨


Okay, so I read this book in one day mostly because I’m doing a book challenge. While I did like this book, it was a bit hard to get through…. 
The plot was quite slow and it switched characters so many times sometimes it was a bit overwhelming.  However it is still a good read, the author writes very well and her plot was a good one, I just wish she would have fleshed a few things out more especially

the villain of the story Tim. Like yes it’s cool that it hits you out of nowhere but at the same time I kinda would have liked more story on him

Spoilers Ahead:
I must say, it took me a while to get into this book, but I was pleasantly surprised by how good it was in the end.
We started off really slowly, following multiple POVS throughout the story. We start off with Ella, the 'Witness', who spots two men getting friendly with two very young girls on the train. As the story continues, we find out that they are felons, just released from prison, and Ella wants to get involved, but doesn't, as she realises that it isn't her job to do that. However, she soon regrets that decision.
Anna and Sarah were on their way to London when they were approached by these felons, but only Sarah made it back. At first, a lot of people blame Ella, because she came forward with the evidence but didn't do anything else other than that. She starts to receive threatening postcards, so she hires a Private Investigator, Matt, to look into it for her. She assumes it's Anna's mother, as Ella once visited her after learning of Anna's disappearance, but there is no evidence to suggest it so far.
Sarah feels guilty about Anna's disappearance, so she lies about her whereabouts that night. It is true, they were talking to the felons, but also, she wanted one of they boy's attention so badly that she told Anna to just go home when she asked if they could leave. That was the last time she saw Anna. She TW overdoses on pills, as she thinks about the fact her father might be involved. When she was younger, she was TW sexually assaulted by him, but she didn't think to tell anyone. But then, she finds out her sister, Lily, went through the same thing, and their mother knew but never believed them. They never considered their father's role in her disappearance, until they remember about how many photos he took, and how beautiful he thought Anna was, and Anna even showed Sarah a message about him coming to get her. She finally comes clean to the police. 
Unfortunately, Sarah's father and the two felons have alibis, so the case goes cold, and the chances of finding Anna lowers considerably. They decide to visit Anna's mother again, after a fake hostage scenario in Spain with one of the felons. But when they get there, something isn't quite right. There is a photo of someone in their house, someone who was also on the train with them. Tim, one of Anna's friends, who was said to have had an alibi somewhere that was nowhere near Anna.  
And because of the postcards, Ella has been avoiding work, and she's had to hire some people to do that. Said people are being interviewed by her son, Luke, now. One of them being Tim, who knifes Luke for even just being in the same group as Anna. Luckily, he prevails but they find Anna in a freezer - not alive. Turns out Tim had a problem with anyone else talking to, or even looking, at Anna, and it had reached a creepy obsession. He fell into a coma, but he was arrested and charged for murder in the end. 
The postcards were from Jenny, Anna's sister, although she only sent 2, and Tim sent the rest after he found out what she was doing.  
It was a tough read, but a good read, this book. First of all, can I just say the plot twist? *chefs kiss* I love love LOVE books with a plot twist, and this is one of the greatest ones yet. I had considered just about everyone else, wondering how they were all linked up and everything, and I briefly considered Tim, but it wasn't serious. The observation where Ella finds him in the photo and destroys his alibi? Chills. Literal chills. I loved the whole story, although I did think some bits weren't necessary. Luke's story was a nice addition, but it didn't further the plot or his character development, in my opinion, so it didn't do much for me. And looking into Anna's father, it was made to seem like he'd done something more sinister to her, making him seem more suspicious, when he'd just cheated. Still not great, but definitely better than the alternative. 
I do like the reconciliation at the end, a mutual understanding between Anna's mother and Ella. I think it was very melancholic, after all that not finding Anna alive - I was with the mother, I was sure she'd make it. I don't know why, if Tim liked her so much, why he would do that in the first place? It's very saddening. But a really nice book to read, and a very intriguing plotline and finale. 

I loved this book! It’s very well written and the plot is FABULOUS.
