Antonia is convinced the strange events at The Cloisters museum were only a dream … until, on a winter trip to Norway, she and her sisters cross paths with the familiar dark-eyed museum guard.

Deep in the frozen wilderness, where magic stirs and long-buried family secrets come to light, Antonia must discover where the true danger lies and save her family, before it’s too late.
