In Hilda and the Midnight Giant, our protagonist finds her world turned upside down as she faces the prospect of leaving her snow-capped birthplace for the hum of the megalopolis, where her mother (an architect) has been offered a prestigious job. During Hilda's daily one-and-a-half hour trek to school she looks for ways to stall her mother's decision. She conspires with the beings of the mystical Blue Forest to delay the inevitable. Will they help or hinder her? More importantly, who is this mysterious Midnight Giant?

This is the second part of the Hildafolk series, a series that follows Hilda on her many adventures and travels through the magical fjords and enchanted mountains of her birthplace as she unravels the mysteries of the supernatural world that surrounds her.
