"This lively, full-color science comic explores Phoebe's insides after she acidentally 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"-- Excerpt of summary from book.
