Three haunting novels of romantic suspense from the New York Times-bestselling and Edgar Award-winning "Queen of the American gothics" (The New York Times).   A trio of spellbinding thrillers from "the Grand Master of her craft" (Barbara Michaels) and a "superb and gifted storyteller" (Mary Higgins Clark).   Window on the Square: Megan Kincaid lives in a house of secrets on Washington Square in New York City. Hired by romantic and wealthy Brandon Reid as his stepson's caretaker, she knows the boy's violent history--one the Reid family has tried to bury. But their mysterious past runs deeper and more dangerous than she realized. Now, as Megan slowly unravels the truth behind a tragic murder, she's torn between a child she must save, a man she's come to love, and the desire to run for her life.   Thunder Heights: Camilla King has received a startling invitation: Her wealthy and estranged grandfather wants her to return to the mansion on the Hudson where her mother suffered a mysterious death. Camilla complies, partly to meet the family she never had, and partly because of whispers of an inheritance. But a series of suspicious accidents lead Camilla to fear that her homecoming may be a carefully designed trap--the same one her own mother fell prey to many years ago.   The Golden Unicorn: After the death of her adoptive parents, Courtney Marsh is determined to uncover her past. The only clues are a unicorn pendant she's had all her life and a newspaper clipping about a prominent yet reclusive East Hampton family. Under the guise of a reporter, she's arrived at the Rhodes's mansion to find the truth of her heritage. But the more Courtney discovers, the more she fears--because hers is a legacy of murder that has yet to play its final hand.
