Here is the true story of how four Americans and one Cuban tracked down a killer, one of the word’s most vicious plagues: yellow fever. Journeying to fever-stricken Cuba in the company of Walter Reed and his colleagues, the reader feels the heavy air, smells the stench of disease, hears the whine of mosquitoes biting human volunteers during surreal experiments.

“[A] powerful exploration of a disease that killed 100,000 U.S. citizens in the 1800s.” —Kirkus Reviews
