In the third book in the New York Times bestselling series, Frank Einstein (kid-genius, scientist and inventor) and his best friend Watson, along with Klink (a self-assembled artificial-intelligence entity), and Klank (a mostly self-assembled and artificial almost intelligence entity), once again find themselves in competition with T. Edison, their classmate and archrival—this time in the quest to unlock the power behind the science of the human body.

"Scieszka's third joke-filled Frank Einstein adventure jam-packed with sneaky science lessons is perfect for young scientists who may prefer fact to fiction. Biggs' ample tricolor (orange, black, and white in this outing) illustrations extend both the story and the science. Aftermatter broadens the fun with additional science facts, puzzles, and even baseball tips. Halfway through the series, the science and the sly (and slapstick) laughs are still going strong." - Kirkus

"A perfect page-by-page balance of nerdy science and zany humor will draw readers in and keep them moving." - Booklist
