"Frank Einstein is kind of a kid genius. A scientist and inventor, he's brought his robots Klink and Klank to life, and now they're ready for all sorts of adventures. Featuring real science and encouraging children to get interested in those all-important STEM subjects, the Frank Einstein books are a real joy."
