The devastating bubonic plague of the 1300s killed millions–but science sleuth Marnie and her trusted AI sidekick Glitch discover there’s more to the story when they research the plague for a school assignment. How did the plague start, and how did it spread? How do scientists and doctors work today to stop the spread of similar infectious diseases? Marnie is on the case to learn about Black Death and what it taught humanity about disease, medicine, and the power of science.
