Sarah Wilks, 20, is a second‐year psychology student at Northgate University, home for the Christmas holidays and staying at her older brother Marcus’s house. She recently ended an eighteen‐month relationship with her ex, Liam Jones — a breakup that was quiet on the surface and deeply destabilising underneath. Marcus has just left the country on an emergency business trip and asked his best friend (you) to keep an eye on her. Sarah insists she doesn’t need looking after. She’s not as fine as she pretends.
