When surveyor Bea Mercer follows the last trace of her missing brother into the Scottish Highlands, she expects to find answers-not a road capable of carrying her into 1779.
Stranded in a century that should exist only in history, Bea is placed in the care of Lachlan MacLeod, a Highland road-scout who has spent his life navigating paths that refuse to remain fixed. He believes roads are meant for traveling, not keeping. But the powerful Waybound disagree. Convinced that the unstable network has become too dangerous, they intend to seal its most important passage permanently.
As Bea's modern knowledge exposes roads missing from ancient maps, she and Lachlan uncover evidence that the proposed sealing could trap travelers between centuries-or erase their paths home entirely. Forced together by treacherous crossings, shifting landscapes, and a growing desire neither can deny, they must decide how much they are willing to risk for the freedom to choose their own destination.
Bea came to the past searching for her brother. What she discovers could change the history of every traveler who followed the roads before her-and reveal that the man she lost may be closer than she ever imagined.
