"As the pampered pet mouse of an ambassador's son, the lovely Miss Bianca is both a seasoned world traveler and a talented diplomat. So when the members of the Prisoners' Aid Society, a venerable mouse organization, decide to rescue a Norwegian poet from the grim Black Castle, they turn to Miss Bianca to lead the way. Though hesitant at first, Miss Bianca quickly takes the prisoner's cause to heart. After all, she's a poet herself. With the help of Bernard the Pantry Mouse and Nils, a happy-go-lucky sailor, she sets off on a daring journey to the darkest corner of Scandinavia--a journey filled with adventure, intrigue and just a touch of danger." --container.
