Franny K. Stein believes that nothing in the world compares to being a mad scientist and she is absolutely convinced that, given the opportunity, every kid in her class would feel the same way! So Franny makes it her mission to help her classmates find their own inner mad scientist. All she needs is a few open-minded classmates, a half-completed two-headed robot and an invisibility potion. Let the laughter begin!
Not sure why the exact title does not come up, but this is the "The Invisible Fran" - FKS #3. DD really enjoyed these books.
