The Winter Sea by Susanne Kearsley.
Is genetic memory just a theory or does it actually occur, or maybe the protagonist in this novel just has a really good imagination?
American historical novelist, Carrie McClelland journeys to Scotland to research her new book concerning an early planned Jacobite invasion in 1708. Her story and her research focus on Slain's Castle, now open to tourists, which was the center of much of the plotting in 1707 and 08. Carrie is soon dreaming of her ancestors who were involved in the intrigue. Is she channeling her long ago many times over great grandmother, is her new romantic interest also a descendant or is it her writer's imagination at work.
