Book excerpt: In West of the Moon, award-winning and New York Times bestselling author Margi Preus expertly weaves original fiction with myth and folktale to tell the story of Astri, a young Norwegian girl desperate to join her father in America. After being separated from her sister and sold to a cruel goat farmer, Astri makes a daring escape. She quickly retrieves her little sister, and, armed with a troll treasure, a book of spells and curses, and a possibly magic hairbrush, they set off for America. With a mysterious companion in tow and the malevolent “goatman” in pursuit, the girls head over the Norwegian mountains, through field and forest, and in and out of folktales and dreams as they steadily make their way east of the sun and west of the moon.
