Lucky Per is a bildungsroman about the ambitious son of a clergyman who rejects his faith and flees his restricted life in the Danish countryside for the capital city. Per is a gifted young man who arrives in Copenhagen believing that "you had to hunt down luck as if it were a wild creature, a crooked-fanged beast . . . and capture and bind it." Per's love interest, a Jewish heiress, is both the strongest character in the book and one of the greatest Jewish heroines of European literature. Per becomes obsessed with a grand engineering scheme that he believes will reshape both Denmark's landscape and its minor place in the world; eventually, both his personal and his career ambitions come to grief. At its heart, the story revolves around the question of the relationship of "luck" to "happiness" (the Danish word in the title can have both meanings), a relationship Per comes to see differently by the end of his life.
