Gulp: Adventures on the Alimentary Canal

Roach (Stiff) once again goes boldly into the fields of strange science. In the case of her newest, some may hesitate to follow—it’s about the human digestive system, and it’s as gross as one might expect. But it’s also enthralling. From mouth to gut to butt, Roach is unflinching as she charts every crevice and quirk of the alimentary canal—a voyage she cheerily likens to “a cruise along the Rhine.” En route, she comments on everything from the microbial wisdom of ancient China, to the tactics employed by prisoners when smuggling contraband in their alimentary “vaults,” the surprising success rate of fecal transplants, how conducting a colonoscopy is a little like “playing an accordion,” and a perhaps too-good-to-be-true tale in the New York Times in 1896 of a real-life Jonah surviving a 36-hour stint in the belly of a sperm whale. Roach’s approach is grounded in science, but the virtuosic author rarely resists a pun, and it’s clear she revels in giving readers a thrill—even if it is a queasy one. Adventurous kids and doctors alike will appreciate this fascinating and sometimes ghastly tour of the gastrointestinal system. 18 illus. Agent: Jay Mandel, WME Entertainment. (Apr.)
