Struggling with the tragic end of her marriage, Keaka Denney is on a bittersweet adventure in Scotland with her son, Colin. She's joining him on a weeklong hike along the West Highland Way before he enters university in Glasgow. Soon into the journey, Keaka's disquieting visions begin -- a woman from ages past reaching for Colin, a burning cottage, violence. Scotland, 1801. After Sorcha Chisholm and her son are wrenched from their home in a brutal eviction, they face an arduous trek toward a new beginning. When Sorcha learns she's wanted for a murder she didn't commit, she and her son run for their lives. Then help arrives from the strangest woman in the most unexpected ways. Centuries apart, Keaka and Sorcha walk the same path -- devoted mothers in circumstances beyond their control who will do anything to keep their sons safe. Defying logic, they find strength in each other. But what does their connection mean? And how far will it go?
