As children, Mairi and Colleen were inseparable half-sisters roaming the wooded glen near their home in Killin, Scotland—until an argument between their parents turns violent and changes the future for all of them. After vowing on an ancient Promise Stone to reunite somehow one day, Mairi is taken by her French mother to a new life in Paris. Colleen remains behind with their father—and two young locals, Calum McInnes, handsome son of a Glasgow heiress, and Barry Buchanan, a brooding mysterious artist who will weave their way into the lives of both girls. Years later after Mairi has grown and become Marielle, a respected journalist, she at last journeys home only to find Colleen was the victim of a suspicious accident. In her quest to uncover the truth of her sister’s death, Marielle will enlist bitter rivals, Calum and Barry—neither of whom know her true identity. Deceptions, betrayal, and half-truths abound on the way to the explosive conclusion in a beautiful place that is… Beyond The Glen.
