★''Fritz offers a wickedly funny look at 10 explorers who, between 1421 and 1522, ventured into what contemporaneous mapmakers called the Unknown. While presenting the salient facts, Fritz approaches them with playful irreverence; accordingly, the frequently traveled material can seem refreshingly new." -Publishers Weekly (starred review)
"An excellent book that brings the period alive." -Children 's Book Review Service
''Fritz delivers a pleasant, chatty narrative, chock full of insights, observations, and fascinating facts." -The New Advocate
