La Colline (The Hill) by Mathilde Beaussault: the French thriller about motherhood that blends suspense and emotion

In the spring of 2026, a new novel has fans of suspense and strong emotions talking. Mathilde Beaussault’s La Colline is a remarkable French thriller, combining psychological intensity and human depth. From the very first pages, the story captures our attention with a brutal starting point: an infant abandoned in a container in Rennes, and a seventeen-year-old struggling to survive.

A French thriller that shakes up the genre’s codes

It all begins in the middle of winter, in a cold, anonymous urban setting in Rennes. A newborn baby is found in a container. Alive. A few floors up, a seventeen-year-old girl struggles to survive. This brutal point of departure is immediately gripping.

Then the story unfolds in a different way. In a closed room, Monroe oscillates between present and memories. She plunges back into those months spent on a hill, far from everything, with her grandmother. Up there, the pace is different: slower, rougher too, but strangely soothing.

Between silence, nature and ancestral gestures, Monroe thought she had found a refuge. An interlude. Perhaps even a form of reparation. Yet it’s this contrast that makes the novel so powerful: on one side, the urgency, the city, the violence; on the other, nature, the connection, a certain fragile gentleness.

“A novel that doesn’t just tell a story, but explores what connects us, weakens us, builds us.”

A narrative that plays on tension and emotion

Indeed, La Colline is not just about suspense. The story alternates with finesse between two opposing worlds. On the one hand, the urban coldness of Rennes and its vital urgency. On the other, the hill, a place of retreat and transmission.

What’s more, Mathilde Beaussault builds her plot around Monroe, the central character whose memories are interwoven with the present. This narrative structure allows the reader to gradually grasp what’s at stake in the drama. Each revelation brings its own set of emotions.

The deep themes that make this French thriller so strong

Beyond the suspense, La Colline’ s themes are touching. Motherhood, first and foremost, unfiltered. In all its power and vulnerability. Consequently, the female body is at the heart of the story, in both its suffering and its strength.

The novel is also about transmission. Between women. Between generations. The complex bond between a grandmother and her granddaughter, made of love, unspoken words and gestures, makes a deep impression. It brings to mind those psychological thrillers where emotion is as important as the plot.

The kind you read with a heavy heart, but can’t put down. La Colline is clearly in this vein. This French thriller explores what connects us, weakens us and builds us. What’s more, Mathilde Beaussault is establishing herself as a voice to be reckoned with.

In a literary landscape where suspense is constantly being renewed, La Colline attracts attention for its emotional intensity and deeply human outlook. A book that resonates long after you’ve closed it. Available from Éditions Seuil for €19.90, this novel fully deserves its place among the must-reads of the year.

Emotional writing

Mathilde Beaussault has mastered the art of narrative tension. Each chapter brings its share of revelations, without ever lapsing into sensationalism. However, the author does not hesitate to confront her characters with extreme situations.

What’s more, the style remains fluid and accessible. Descriptions of the hillside alternate with darker urban scenes. In this way, the reader is immersed in two distinct atmospheres, which respond to and enrich each other.
