Drums of Autumn (Outlander #4)

In this breathtaking novel—rich in history and adventure—The New York Times bestselling author Diana Gabaldon continues the story of Claire Randall and Jamie Fraser that began with the now-classic novel Outlander and continued in Dragonfly in Amber and Voyager. Once again spanning continents and centuries, Diana Gabaldon has created a work of sheer passion and brilliance.... 
It began at an ancient Scottish stone circle. There, a doorway, open to a select few, leads into the past—or the grave. Dr. Claire Randall survived the extraordinary passage, not once but twice.
Her first trip swept her into the arms of Jamie Fraser, an eighteenth-century Scot whose love for her became a legend—a tale of tragic passion that ended with her return to the present to bear his child. Her second journey, two decades later, brought them together again in the American colonies. But Claire had left someone behind in the twentieth century—their daughter, Brianna....
Now Brianna has made a disturbing discovery that sends her to the circle of stones and a terrifying leap into the unknown. In search of her mother and the father she has never met, she is risking her own future to try to change history ... and to save their lives. But as Brianna plunges into an uncharted wilderness, a heartbreaking encounter may strand her forever in the past ... or root her in the place she should be, where her heart and soul belong...
