STARRED REVIEW Publishers Weekly
"Scathing and illuminating. . . . [M]uch of the scientific community and the popular press accepted the idea that a meteor colliding with the Earth was responsible for the planet’s fifth mass extinction. Keller, however, had her doubts, and worked tirelessly to gather data. . . . Her results are shocking."
The New York Times
"Gerta Keller . . . is rattling the foundations. And the theory she supports . . . has unleashed a small tempest of its own among die-hard believers in the meteor theory, who are known as 'impacters.' . . . Keller argues that, besides a series of meteor impacts, the extinction of the dinosaurs was preceded by an intense period of volcanic eruptions that altered the climate. . . . All this makes her a maverick."
The Atlantic
"A Princeton geologist has endured decades of ridicule for arguing that the fifth extinction was caused not by an asteroid, but by a series of colossal volcanic eruptions. But she's reopened that debate. . . . This dispute illuminates the messy way that science progresses and how this idealized process, ostensibly guided by objective reason and the search for truth, is shaped by ego, power, and politics."
