Time is theirs to keep. But it comes with a price.
In the early 23rd Century, vampires learned how to travel back in time, and created a time-tsunami that threatened life as we know it, until they corrected their mistake. They created the Chronometric Conservation Agency, tasked with preserving history and protecting humanity's future. The Touring arm of the Agency offers trips back into the real past, with vampire guides called travelers.
When Natalia (Tally) Marta, vampire and traveler, takes her client to visit the siege of Stirling Castle in 1314, she is caught and held hostage by Robert MacKenzie, a Bruce clansman. Rob is drawn to the wilful, stubborn and very different English lady and their relationship becomes an intimate, highly-charged sexual pairing. Tally and Rob realize their bond is more than sexual, that the emotions stirring their hearts are true. Christian Lee Hamilton, vampire, one of the last true southern gentlemen, and Tally's ex-lover, knows the 1314 time marker well enough to jump back and help Tally return home. His arrival at Bannockburn adds complications, for Christian finds himself drawn to Rob MacKenzie as much as Tally is. But neither of them can stay in the past forever. To do so means certain death.
