This would be a good book for teens or adults who want a quick introduction to Jamestown. I found it a quick and easy read after the first chapter. The author obviously derives much of her information from primary sources but has a knack for not burdening the reader with too much detail. She is far more likely to include something fun, like the number of piglets that were born at such-and-such a time, than to weigh the new comer down with too much discussion of the Virginia Charters.
Overall I thought it was intelligently written. First published in the 1950's the material facts have been updated. (It was not clear to me by whom. But since the preface by a gentleman from the National Parks Service, I assume it was one or more of the curators at Jamestown.) There are several useful maps included.
