I stand at the front door and meticulously check my reflection in the glass. I must look perfect to meet Lou’s new boyfriend. I haven’t been invited but best friends don't require invitations, right? Scott 's arrival coincides with Donna 's, leaving me with no choice but to welcome her in, though I've made it clear she's an unnecessary addition to today's gathering. This meal is about introducing Scott to my mother and daughter – a fact Donna conveniently ignores. As the introductions unfold, it's evident that Donna has taken a liking to Scott. Mum's quizzical expression in the kitchen speaks volumes – Why is Donna here? Her presence has always been a constant, demanding focus in my life. Now, however, it's evolving into something deeper, with unsettling imitations and intrusive encroachments into every aspect of my world. The struggle to create distance only seems to intensify Donna's attachment, pulling her dangerously closer. And by the time I realise I’ve risked everything, it’s probably too late to stop her. A gripping and unsettling psychological thriller about what happens when a jealous and obsessive friendship turns dangerous and dark. Perfect for fans of Daniel Hurst and Freida McFadden.
