Lucy Clarke writes destination thrillers in which holidays, remote landscapes and close friendships become sources of danger. The Castaways follows two sisters across dual timelines after a flight disappears near a remote island, One of the Girls turns a hen party on a Greek island into a story of secrets and death, and The Hike sends four women into the Norwegian wilderness where old tensions surface alongside a new threat. Earlier novels such as The Sea Sisters and A Single Breath also use travel and coastal settings to destabilise relationships. Clarke's books are fast, atmospheric and relationship-led, usually narrowing a small group into an isolated place where information is withheld and loyalties shift. They fit psychological thriller, destination thriller and holiday suspense. One of the Girls is a good standalone entry point for group dynamics, while The Castaways adds a survival element and a more elaborate structure built around disappearance, isolation and what happened before the characters became stranded.
