A New Day Rising (Red River of the North #2)
Lauraine Snelling

When spring appears, Roald's distant cousin Haaken arrives to help with the heavy field work, and Ingeborg is able to once again concentrate her efforts on home and children. After the bleak winter, she cannot ignore the joy that Haaken brings to their lives or the attraction she begins to feel toward him. When Roald's brother from Norway also arrives to help the family, things become very complicated around the simple prairie dwelling!
He reminded her of a Viking of old--
could he be persuaded to stay?
