"Well-timed . . . compelling . . . Kennedy's book manages to end on a somewhat hopeful note. Yes, our trajectory is defined by microbes. But it's also influenced by our reactions to them--and our acknowledgment of their power."--The Atlantic

"[Pathogenesis] shines when it brings cutting-edge science to bear on these questions, something that Kennedy treats with great care. . . . Pathogenesis shows a microbial world that is as complex, dynamic, and alive as the human one, and just as consequential."--Financial Times

"Great historical changes are often conceived of as being brought about by the genius and tenacity of great men, or occasionally women, but Jonathan Kennedy argues that germs are largely responsible for everything, from the decline of the Neanderthals to the current poverty of sub-Saharan Africa. . . . [He] offers a different lens to view many of the big events of the past."--Associated Press

"The fluency of Kennedy's narration is remarkable, weaving Tolkien, Game of Thrones, and Monty Python into memorable and accessible explanations of genetics, evolutionary biology and demography. . . . Impressive and enjoyable."--The Spectator

"A virtuoso analysis of the fallout from encounters between deadly viral and bacterial pathogens and human populations that lacked immunity. . . . The result is a fascinating look at history from the perspective of its tiniest protagonists."--Publishers Weekly (starred review)

"It's not often you pick up a book that promises to alter your entire understanding of the story of humanity."--Lit Hub

"Thrilling and eye-opening . . . Jonathan Kennedy explores the enormous role played by some of the tiniest life on earth: the power of plagues in shaping world history."--Lewis Dartnell, author of The Knowledge
