A thousand years ago, the Viking colony of Vinland was ravaged by a swift-moving plague ... a curse inflicted by the sea god Ægir. The last surviving Norseman set the encampment and his longboat ablaze to ensure that the disease would die with him and his brethren.
In present-day Norway, a distinguished professor is found murdered, his priceless map of Vinland missing. The ensuing investigation leads to the reclusive world of Lindsey Nolan, a scientist and recovering alcoholic who has been sober for five years. Lindsey reluctantly agrees to help the detective who's hunting the murderer, but she has a bigger problem on her hands: a mysterious disease that's spreading like wildfire through the population of Woods Hole. As she races against a rising body count to discover the source of the plague, disturbing events threaten her hard-won sobriety--and her life. Will Lindsey be the next victim of Agir's curse?
