I’ve seen this compared to Agatha Christie but I’ve also seen another review say that the only similarities are that they’re on a train and there’s a murder and I have to agree. The only thing I would add is that each character does have their own motive and secrets but I don’t feel it was as complex. There are a few other nods to Christie but that’s about it. The entire plot is pretty straightforward but we’re following the characters and multiple POVs so it takes a while to get to the meat of the story. It’s very character driven and all the characters are well thought out, some more interesting than others. The ending really saved this book. There was a last minute plot twist that I did not see coming. It was really heartbreaking too. I understand that all of the character backstory and buildup was needed to really feel the gut punch of the twist but you can’t tell that when you’re reading it. Overall it was an interesting idea but I just feel like it took too long to get there
