In the early 23rd Century, vampires learned how to travel back in time, and created a time-tsunami that threated life as we know it, until they corrected their mistake. They created the Chronometric Conservation Agency, which is tasked with preserving history and therefore protecting humanity's future. The Touring arm of the Agency offers trips back into the real past, with vampire guides, called travellers. When Natalia (Tally) Marta, vampire and traveller, takes her client to visit the seige of Stirling Castle in 1314, she is caught and held hostage for ransom by Robert MacKenzie, a Bruce clansman. Rob finds himself drawn to the willful, stubborn and very different English lady he has captured and the relationship becomes an intimate, highly-charged sexual pairing. Swiftly, 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 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.
