Viking Quest Series by Lois Walfrid Johnson

When Bree learns that her brother, Devin, her sister, Keely, and her friend, Lil, will set out for Ireland, she longs to go with them. Instead, Mikkel asks her to be a cook for voyage to Greenland. Somehow her excellent food becomes inedible and the Vikings think she's trying to sabotage their voyage. Join Bree and Devin for more adventures in this fourth installment of the Viking Quest series.

Three years after their first adventure began, Bree, Devin, and Mikkel now enter a new world with the explorer Leif Erikson. Their first task: build a shelter to survive the winter. But danger lurks from within the shadows on the horizon of a life where everyone needs the courage to win. Can Mikkel conquer his enemies and find new purpose for his life? Will he keep his promise to Bree and Devin to take them home to Ireland? Will he keep his pledge of honor, even if it means death?
