This book doesn't offer a heck of a lot for the adult reader unless they're extraordinarily ignorant about historians, but it is a great middle-grade and lower high-school book which is where I donated it once I'd read it. The subtitle is "How we know what we know about the past." It's heavily biased towards US history, but it does not neglect historical and archaeological questions elsewhere, so we get coverage of Stonehenge and other such henges, of the so-called great wall of China, Roman ruins in Italy, and even cave paintings in France. Sadly, Africa gets no coverage.
That said, the author does offer some engaging stories about historical misunderstandings, such as that over the Battle of Little Big Horn, and who really did discover the Americas. The chapters are brief, each covering a different historical event or people, so we learn about gunboats in Lake Champlain, The Edmund Fitzgerald on lake Superior, which is big enough to be a sea if only someone would dump enough salt in there, Martin's Hundred, Mesa Verde, Herculaneum and Pompeii, and even Noah's ark! The Old Testament has it wrong! Who knew?!
I think this is a great introduction for young people to history, which is a subject that's all too often overlooked or under-served, and I recommend it. And it's written by a provost!
