Rhiannon has spent her life being a quiet wallflower – a literal doormat for everyone around her, taking comfort in a secret kill list she tots up in her head.
Living as the dormouse receptionist at the local paper, she spends her days without friends, and looking after her sick father, hoping one day to get her break to be a local journalist.
But then newcomer AJ comes in and takes the job, and she's seething – but he seems taken with her.
After years of being tightly wound, a family tragedy sets off a chain of events that pushes her to her breaking point. Not least when her high school bully Julia returns to town with a high-flying job and hunky fiancé, Marcus, yet for some reason still seems intent on ruining her life.
Her sister proves little help either, in fact adding fuel to the fire.
When she's crossed one too many times, Rhiannon finally takes her father's advice and stands her ground – with horrific consequences.
