Courageous men who left an indelible mark on history during their lifetimes come alive on the two discs in this audio book. And, yes, only men are included in this title, which is one in the publisher's "Junior Classics" series. Listeners travel to exotic places with the explorers Marco Polo, Captain Cook, Lewis and Clark, the astronauts on the Apollo mission, and five others. The subjects included took bold risks on their journeys to expand understanding of the world in which they lived. Children will be inspired as they learn about these men and their adventures. The narrators are adept at conveying the dangers and accomplishments of the journeys undertaken to broaden our horizons. Classical music is featured in each clip. Teachers and librarians may want to use this audio book to introduce choices for biographical subjects/reports in the classroom. It is also an excellent diversion on car trips and rainy days. Family listening will encourage discussion about the explorers and the time periods in which they lived. Total listening time is approximately 2 ½ hours. Reviewer: Jeanne K. Pettenati, J.D.
