Both Publishers Weekly and Kirkus Reviews, whose reviews inform the purchases of bookstore buyers, have nice words for The Fever. PW calls the book “fascinating, mordant” and “absorbing,” while Kirkus calls it a “sobering account” with “important lessons.” Excuse me for focusing unduly on the praise. I should add that they both also give typically concise summaries of the book, which should prove useful for interested readers. The full reviews are here (Publishers Weekly) and here (Kirkus).
