Fifteen year-old equestrian prodigy Roan Montgomery has only ever known two worlds: inside the riding arena, and out. Both are ruled over by her father, who demands strict obedience in all aspects of her life. However, the warped power dynamic of coach and rider extends far beyond the stables, and Roan's relationship with her father has long been incestuous. A ruthless ambition for the Olympics allows her to compartmentalise this dark aspect of her life, until she meets Will Howard, a boy her age, who brings everything into focus.
