Invisible Battlefield: Whether the reader is interested in the history of medicine, intrigued by the origins of the Covid-19 pandemic, or fascinated by the medical discoveries, "The Invisible Battlefield" promises to be an enlightening and memorable read. The book offers crucial insights into our present by exploring our past. The author weaves an intricate tapestry of stories that reveal the immense political, social, and psychological impact of epidemics. Unusual for a book of this genre, it presents not just an academic treatise, but also a vivid biographical and autobiographical saga that combines historical analysis with the author's unique perspective. As a stark example, the text unravels the mysteries of the pneumonic plague and smallpox outbreaks in mid-20th-century Moscow, shedding light on the complex interplay between public health crises and government control. The historical novel "Eight Days of Quarantine" reveals how the secret police, honed by the harrowing Great Terror, quickly identified and isolated those in contact with a plague patient in a covert operation, preventing the outbreak from becoming an epidemic. If adapted for the screen, this historical novel could serve not only as a gripping medical thriller, but also as a powerful metaphor for a Covid-19 epidemic. The chapters on the origins of the Covid-19 pandemic and the author's family's experiences in Venice during the horrific first Covid-19 wave read like a detective story. The book is not only highly informative, but also incredibly engaging and relatable.
