The Gemini Game (Avalon Mysteries)1994

After the death of her grandfather, Karen Caldwell fled Seven Oaks, leaving her family and its prestigious thoroughbred stables -- as well as the bad memories -- behind. She moved north to Pittsburgh, started a successful clothing business, and began a new life. Now, eight years later, another death mysteriously summons her home. But her family is not pleased by her sudden reappearance, and no one will admit to sending her the telegram informing her of her brother Alec's death. When Nick, Alec's twin, hints that the death was no accident, Karen's search to uncover the truth leads her deep into a web of deceit and family secrets. To make matters worse, when Karen begins to have "accidents" of her own, she finds that the only person she can trust is the irritating but seemingly honest stable manager, Greg Slater . . .
