Facets - Barbara Delinsky

When Hilary Cox sees her long-time lover announce on public television that he plans to marry another woman, she decides to write a tell-all expose about the mining magnate and his sordid
past.
Also seeking revenge is John's sister, Pamela St. George, who attempts to dissuade Hilary from completing her memoir, suggesting that there are more insidious ways to achieve her goal.
Having suffered years of abuse at the hands of John, Pamela is determined to gain control of the family's tourmaline mining business.
While Hilary confronts the demise of her relationship, Pamela struggles to reconnect with Cutter Reid, a man she has always loved but whom John has always kept from her.
As Hilary discovers more about John than she bargained for, three decades of power, duplicity, and money culminate in a thrilling finale with one of Delinsky's most memorable villains.
