Linnea Hartsuyker is a graduate of NYU's Fiction MFA program and Cornell University's Engineering school, and has been researching the rise and reign of Harald Fairhair since she first discovered she was descended from him at the age of seventeen, when her family traced its ancestry back through 1200 years of Swedish and Norwegian church records.

Since then she has read extensively of Icelandic sagas, kayaked and skied the fjordland settings for this novel, and even become proficient in lifting Husafjell stones, as the Vikings did to become stronger.
