Epidemics of encephalitis lethargica—sleeping sickness—have long inspired literature, writes Memphis-based science author Molly Caldwell Crosby in Asleep: The Forgotten Epidemic That Remains one of Medicine’s Greatest Mysteries. “Sleeping Beauty,” “Rip Van Winkle,” and “The Fall of the House of Usher” are but three well-known stories written after separate outbreaks of the mysterious illness, which can cause patients to sleep for months or years, if they ever awaken at all. In Asleep, Crosby, author of the 2006 nonfiction bestseller The American Plague, has written a tale as timeless and disturbing as its fictional predecessors. Crosby will read from and sign copies of Asleep at Davis-Kidd Booksellers in Memphis on March 2, and at Davis-Kidd Booksellers in Nashville on March 16.
