Editorial reviews:
Dvorak challenges the conventional wisdom. . . . an envelope-pushing narrative . . . a wonderful storyteller.
—The Wall Street Journal
Far from a dusty tome plodding through plate tectonics, the book teems with life as Dvorak establishes inextricable links between geology and biology.
—Science News
The author leads readers through each major geological era, from the Hadean Eon (starting some 4.7 billion years ago) to the Anthropocene era (that’s us), explaining past and current theories and even where readers can find physical evidence in North America of these eras—evidence as accessible, to millions at least, as New York’s Central Park.
—Booklist
The epic story of the geological history of North America . . . appeals to readers interested in broader areas of science from astrophysics to climate change.
