Dr. Gwyneth Franger is a renowned expert in early medieval England who is set upon learning the truth about the death of Lord Erik, the last descendant of the powerful House of Wareham. Her quest becomes an obsession, a condition that began with the discovery of a portrait of the tall and valiant warrior with which she forms an extraordinary and inexplicable bond.
Digesting troves of mildewed scrolls and source documentation only enhances her belief that Lord Erik was brutally assassinated by a cabal of traitors in the pay of William the Bastard, shortly before the onslaught of the Norman Invasion.
On an archeological dig in Southern England, her team unearths an Anglo-Saxon fortress, a vast citadel built during the reign of Alfred the Great, which she believes was Lord Erik's stronghold. In the midst of her excitement, she is awakened one night from her slumbers by a disconcerting anomaly emerging from the site.
Dr. Franger finds herself transported back to the Dark Ages and at the side of the noble Lord Erik who commands an army of elite Saxon warriors, a swift and mobile force able to deploy quickly throughout the kingdom to ward off invaders.
Witnessing the unrest firsthand, Gwyneth senses that her instincts had been right all along, and she is determined to learn the identities of the treacherous blackguards hiding in the shadows, villains who may well be posing as Lord Erik's friends and counselors.
Will Gwyneth stop the assassins? Is she strong enough to walk away and watch her beloved Erik die? Or will she intervene, change the course of history and wipe out an entire timeline to save the man she loves with all her heart?
