When one of her authors invites her to Wales for the Christmas holidays, literary agent Lyn Ravenshaw hopes to escape the nightmares that have plagued her since the death of her baby five years before. But Lyn's painful memories are brought to the surface when she meets Elen, an emotionally fragile widow with an eight-month-old child. Mysteriously afraid for her son’s safety, Elen seems to view Lyn as his protector.

But what makes Elen so sure that Lyn has been sent to guard little Stevie? With the help of brooding neighbour Gareth Gwyn Morgan, Lyn begins to untangle the myths surrounding the child. As her dreams grow ever more disturbing, she finds herself pulled into an ancient Celtic world of haunting legends, dangerous prophecies, and a child destined for greatness . . .
