Getting used to life in the big city is proving difficult for Hilda. The diminutive explorer is still missing the enchanted valleys and magical friends that surrounded her home in the fjords. But tonight is somehow different; tonight is the night of the mysterious Bird Parade. Finding herself lost on the streets of Trolberg, Hilda befriends a talking raven. Together they encounter all manner of bizarre creatures from outcast Trolls to ferocious Salt Lions and deadly Rat Kings—maybe the city isn't so boring after all.
