Franny K. Stein is a mad scientist who prefers all things spooky and creepy, but when she has trouble making friends at her new school she experiments with fitting in--which works until a monster erupts from the trashcan.

Frannie tries to prevent chaos when her new lab assistant, Igor, a dog of many breeds, accidentally lets loose a giant, fifty-foot, arrow-shooting cupid.

When her embarrassing middle name is revealed at school, mad scientist Franny K. Stein experiments with time in order to return to the past and give herself a more dignified name.

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.

Franny tries to follow her mother's suggestion to change her appearance, but by turning hair styling into a science experiment she creates some very greedy pigtails that terrorize the town.

"Franny K. Stein has had quite enough of her feelings getting in the way. So she physically removes them with the help of one of her machines. But it turns out that not having feelings can make things even worse, especially when you've accidentally released a virus that's turning everybody into toads. Good thing she has the help of her grandma, Granny Fran, and her Sense of Duty to help her shake the apathy"-- Provided by publisher
