A modern tale of love, war, and historical intrigue from New York Times and Globe and Mail bestselling author, Susanna Kearsley.

When Verity Grey is asked to join archaeologist Peter Quinnell’s dig on the Scottish Borderlands, she is thrilled. She has long been drawn to the dark legends of the area, and Quinnell has spent his whole life searching for the resting place of the invincible ninth Roman Legion, which marched from York to fight the Northern tribes before mysteriously vanishing from the pages of history.

But after her first day on the job, Verity isn’t sure she’s made the right decision. Her eccentric boss is convinced he’s finally found what he’s been looking for—not because of any scientific evidence, but because a local boy has “seen” a Roman soldier walking in the fields, a ghostly sentinel guarding the bodies of his long-dead comrades.

Despite Verity’s misgivings, it soon becomes clear that there must indeed be secrets lying beneath the windswept shores, because someone is intent on sabotaging the dig. What do the sentinel’s urgent warnings mean? And who is trying so desperately to drive the team away and keep what is buried hidden?
