Sea Changes — Kay Stephens

When her Yorkshire family is shaken by news of the German occupation of Norway in 1940, Rachel Skelton takes leave from her military hospital to cross the North Sea and rescue her grandmother, Hedda, from Bergen. During her short stay there Rachel is reacquainted with Olav Larsen, a distant relative. But Olav has changed since her pre-war visits, and Rachel immediately feels that he fills a long-felt gap in her life.
