The Fran with Four Brains (Franny K. Stein, Mad Scientist #6) by Jim Benton
Being a mad scientist in the modern world is very hard work. With so much that needs to be done in such a short period of time, multitasking can get way out of hand. Franny needs some additional help. But for Franny there is only one person in the world she trusts to help her with her experiments — herself. So she acquires assistance the mad-scientist way, by building a few real, live, steel-plated Franbots.
Another great Franny K. Stein adventure. Amber absolutely loves this series, mostly because it’s about a girl who loves science and gross things, just like Amber. Her favorite part of this one was the food ray, one of the Franbot accessories. Amber is almost 9 and this series is a little below her reading level, but that makes it fun. She doesn’t have to worry about the actual reading, she can just breeze through it and really enjoy the story.
