Harriet Hamsterbone doesn’t go looking for trouble. Somehow it always finds her. So she isn’t completely shocked when a salesman attempts to sell her some magic beans, or when one of those beans grows into a towering beanstalk leading up into the clouds. But even Harriet is surprised to find a giant castle - complete with one very poetically challenged giant - at the top of it. And she certainly never thought she would make a new friend named Strings who is half harp, half hamster. But Strings isn’t the giant’s guest - she and a rather large goose are his prisoners! This calls for a heroic rescue, and Harriet is just the hamster for the job.
