Kellen Stewart Books in Order

The Kellen Stewart books are contemporary Scottish crime novels, but they do not feel like standard police procedurals. Kellen is a therapist, not a detective, and that matters. She gets pulled into trouble through friendship, loyalty and professional duty, so the crimes always land close to the heart.

Kellen moves in a world of doctors, pathologists, scientists and other clever, overworked people. In Hen's Teeth, a suspicious death on a farm drags her into a knot of grief, old relationships and dangerous research. In Night Mares, the pressure shifts to the veterinary world, where horses are dying after surgery and one of Kellen's closest friends seems to be coming apart. By Stronger Than Death, the threat comes from a shared past that has never really stayed buried.

These are books where expertise matters.

Scott uses medicine, pathology and psychology not as decoration, but as the engine of the plot. The questions are often practical at first, how did this person die, who benefits, what has been missed, but they quickly widen into questions of trust. Kellen has to decide when to act as a professional, when to act as a friend, and when the rules are no longer enough.

The setting matters, too. Glasgow and the wider Scottish landscape give the series its weather, pace and mood. There are farms, clinics, labs and city streets, and all of them feel lived in. Scott is very good on the way work shapes people, and on the way private loyalties can make a crisis sharper, not simpler.

Another thing that makes this series stand out is its focus on women with long histories, shared wounds and messy personal ties. That gives the books an emotional charge you do not always get in crime fiction. The danger is real, but so is the sense that people are trying, imperfectly, to look after one another.

They are tense books, but human ones.
