Women have long been overlooked or underrepresented in the history books.  This collection of biographies about female explorers is a positive step toward recognizing these courageous women and their contributions.  The ten women explorers who are featured, with four pages of text and illustrations each, include Louise Arner Boyd, Nellie Cashman, Ynes Mexia, Lucy Evelyn Cheesman, Annie Smith Peck, Alexandrine Tinne, Delia Julia Denning Akeley, Violet Cressy-Marcks, Freya Stark and Daisy Bates.  These mini biographies give a snapshot of each woman’s life and accomplishments, written in well-organized text which is easy to read and understand.  There are several colorful and expressive illustrations for each biography which compliment the text nicely.  I learned a lot reading this book and discovered heroes I was not familiar with before.
