With "Silverhill," Phyllis A. Whitney repurposed some of the elements that had already made her earlier romantic suspense novels hits. A young woman discovers the ancestral home from which she has been exiled ("Sea Jade," "Thunder Heights," "Trembling Hills") and experiences hostilities, if not outright cruelty from the relatives whose lives will be disrupted by her arrival (again, "Thunder Heights" and in particular, "Sea Jade"). Charged with a task by her dead mother, spirited Malinda James takes on her autocratic grandmother Julia Gorham and becomes a disrupter and agent of change (see also "The Quicksilver Pool"). As was her wont, Whitney shades her characters a little more maturely than her counterparts/rivals (Victoria Holt, Mary Stewart, Velda Johnston), even if the romantic plots are never quite as convincingly done (Holt was the leader in this, thanks to sparring, witty dialogue). The novel is short, entertaining and if not that original, even within the author's own oeuvre, it's well-written and its evocation of mental illness and obsession is compelling.
