Kagaku Manga Survival

Begin an epic journey through the human body with a look at the digestive system. This lively, full-color science comic explores Phoebe’s insides after she accidentally swallows a microscopic ship. The only problem? Dr. Brain (the ship’s eccentric inventor) and Phoebe’s friend Geo are on board! Geo and Dr. Brain must avoid danger at every turn—like hazardous stomach acid and feeding parasites. (Ew!) Will they escape? You've got a front-row seat as they travel through Phoebe’s esophagus, stomach, and intestines.
