Description

Franny K. Stein is back with another laugh-out-loud experimental adventure in the ninth book in the Mad Scientist series from Jim Benton, the New York Times bestselling author-illustrator of the Dear Dumb Diary and It’s Happy Bunny series.
Franny K. Stein isn’t a good baker. But when she sees that the fundraisers for the art and music departments at her school aren’t making enough money, she decides to take matters into her own hands. Using her genius mind and kitchen, which is really just another type of laboratory, she sets out to create The Most Delicious Muffin On Earth! Sales, of course, go through the roof. But bad things can happen when people become exposed to the best thing they’ve ever tasted. They can become…overenthusiastic.
