A historian unearths archaeological proof the Vikings reached New England a thousand years ago. Rather than academic fame, her discovery leads to encounters with the descendants of those voyagers and the still powerful enemy that drove their forebears to seek refuge in 'Vinland' - North America. That enemy, even today, seeks to retrieve treasures Leif Eriksson looted from it - and erase what some of those relics could reveal.
Shielded by something extraordinary, the secretive exile colony has survived for a millennium in the shadows. As threats close in, the historian believes she can expose their pursuers while keeping her new allies safely veiled. Further astonishing discoveries strengthen her hand - but also expose her to deadly dangers.
