Introduction

Rosamund Lupton’s Three Hours is a gripping standalone thriller that unfolds over the course of a single, harrowing morning during a school siege. Known for her psychologically nuanced and emotionally centred writing, Lupton creates a story that is both urgent and deeply humane. Even when everything seems dire, community and bravery can come together and come out on top, if not with some scars.


A Summary

Three Hours takes place in a school under siege from a school shooter whose motives are unknown. As the staff and students scramble to protect one another, the narrative shifts between classrooms, parents racing to reach their children, and investigators trying to piece together what led to the attack. The story unfolds in real time, heightening the tension as fear, confusion, and small acts of bravery ripple through the building. While the threat remains immediate and terrifying, the novel also explores community, resilience, and the fragile connections that hold people together when everything familiar begins to fracture.

Writing Style

Three Hours covers many different POV’s, all in third person, but not once did I feel confused who was front and centre. Lupton’s writing style focuses on the tension, and the thoughts of the characters, which keeps the book fast-paced but hard hitting. The chapters vary in size, typically between 10-30 pages, but the constant change in whose POV you are in keeps it fresh and the plot moving.

What I Loved

It is incredibly obvious how much research Lupton did to make this book - and it paid off in an amazing way. There are many POV’s in this book, and all of them feel interesting, which is so difficult to achieve, but I never felt bored of a specific set of characters. This was especially true for the POV on Beth Alton, the parent whose child is missing. Being inside her head and experiencing her emotions was genuinely heartbreaking for me to read, and it felt so real. Rafi and Basi’s POV, and how their PTSD is present but different for each of them, felt well done. I was hooked and simultaneously didn’t want to read any more because I was scared of what was going to happen next. The psychology of the children stuck in the library, in comparison to those in the theatre created an interesting dynamic, almost feeling like those on the front lines in comparison to those in a base; both definitely have trauma, but their experiences are so vastly different that it appears like two completely different situations. This book is not one where you are constantly trying to figure out who the shooters are. I had guessed who they were fairly early, but no matter when you figure it out, it still feels shocking. The book used the mystery of the shooter’s identity to hide the real plot twist, and I was shaken to my core when I read it.

What I Didn’t Love

The only thing I didn’t love is that I will never be able to read it for the first time again.

Recommendation

Absolutely go read this! This is not a typical, run-of-the-mill mystery or thriller, this tells a story like no other and provides so much heart-breaking clarity on school shootings, refugees, white supremacy and mental health problems. It is definitely a difficult read but it is incredible.

Songs
