Frank Einstein and the BrainTurbois the third book in the New York Times bestselling chapter book series from author Jon Scieszka and illustrator Brian Biggs.

Science fiction meets science fact! Frank Einstein (kid genius, scientist, and inventor) and his best friend, Watson, team up with Klink (a self-assembled artificial intelligence entity) to create the BrainTurbo to power-boost the human body and help their baseball-pitching pal Janegoodall make the team.

But when Klank (a mostly self-assembled and artificial almost intelligence entity) goes missing, they must first rescue their robot pal and stop T. Edison—Frank’s classmate and archrival—from stealing their latest invention and using it against them!

“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 Reviews
