In the medieval city of Paris, fifteen-year-old Princess Gisele bears witness to her father's historic efforts to negotiate a peace treaty with the notorious Viking warlord Rolf, a villain who is known throughout the land by his fierce battlefield alias, Rollo. It is only after the negotiations have concluded that she learns her fate--to become the warlord's wife.

A Viking chieftain of renown, Rolf leads thousands of warriors. Experienced and cunning, he senses that the era of unrestrained violence by Northmen is coming to a close. His marriage to Gisele marks an opportunity for their two peoples to put an end to bloodshed. He moves quickly to settle his men on the land he has been given around Rouen.

Rolf's sovereignty over the land, granted under the terms of the fragile peace treaty, is threatened on all sides by scheming enemies. Noblemen in Paris resent the king's offer of peace with their old foe. A Danish king covets the land. And disaffected men within Rolf's own ranks plot to overthrow him.

Is his young wife, Gisele, the ally Rolf needs to meet these challenges? Can she adapt to her role as wife of this strange and violent man?

Gisele and the Northman is a fictional novel set in the turbulent era of tenth century France.
