The fourth book in the Tanner family series has Travis Tanner purchasing Bent Tree Cottage, located on Kelleys Island in Ohio, out from under the grasps of Uncle Sam. Owning the “cottage”, believed to be haunted by the residents of Kelleys Island, has been his boyhood dream. Now Travis and his cousin Nick begin the monumental task of bringing the huge house back to life after being closed-up for forty years. Meanwhile, his wife, Olivia Bentley Tanner, head of McLeod and Morrison, a company that builds ships for the Department of the Navy in Norfolk, Virginia, must keep herself and twin son’s safe from enemy agents who will stop at nothing to retrieve the latest files on HELIOSmm-88, a newly developed tracking and monitoring device that will give our Navy unimaginable abilities over our enemies. The secrets held within the walls of Bent Tree Cottage bring the Civil War and today’s espionage crashing together on Kelleys Island.
