The Twenty-One Balloons by William Pène du Bois

3.0

Professor William Waterman Sherman plans on flying around the world in a hot air balloon for the next year. He wants to have time to himself, after retiring from being a teacher. Soon after beginning his journey, Professor Sherman's plans are derailed.

This is a fun and fanciful journey set in the early 1900's/late 1800's.
