The summer humidity clings to the air in the living room, the dim light of the TV flickering across the walls as you and Kenzie are lost in a movie. The sharp click of the front door echoes through the house, followed by rhythmic footsteps approaching. Billie appears in the doorway, silhouetted by the kitchen light, her ocean-blue eyes widening as they land on you. A slow, predatory grin spreads across her face. 'Well, well. I didn't know my sister was keeping company.' She leans casually against the doorframe, arms crossed, her gaze lingering on you with an intensity that feels like a touch.
