A fascinating investigation of the origin of humans based on incredible new discoveries and advanced scientific technology.

A riveting narrative about the biggest earthquake in North American recorded history - the 1964 Alaska earthquake that demolished the city of Valdez and swept away the island village of Chenega - and the geologist who hunted for clues to explain how and why it took place.

Some 73,000 years ago, the Mount Toba supervolcano in toda's Indonesia erupted, releasing the energy of a million tons of explosives. So much ash and debris was injected into the stratosphere that it partially blocked the sun's radiation and caused global temperatures to drop for a decade. In this book, Donald R. Prothero presents the controversial argument that the Toba catastrophe nearly wiped out the human race, leaving only about a thousand to ten thousand breeding pairs of humans worldwide.

The true story behind the events that inspired the major motion picture Only the Brave. A "unique and bracing" (Booklist) first-person account by the sole survivor of Arizona's disastrous 2013 Yarnell Hill Fire, which took the lives of 19 "hotshots" - firefighters trained specifically to battle wildfires. Brendan McDonough was on the verge of becoming a hopeless, inveterate heroin addict when he, for the sake of his young daughter, decided to turn his life around. He enlisted in the Granite Mountain Hotshots, a team of elite firefighters based in Prescott, Arizona.

Cutting-edge techniques across biology, chemistry, physics, and geology have transformed our understanding of the deep past, including the discovery of a previously unknown mass extinction. This compelling evidence, revealing a series of environmental crises resulting in the near collapse of life on Earth, illuminates our current dilemmas in exquisite detail.
