A young girl helps fix machines around town in this delightful introduction to engineering. Franny Fixit can fix anything. She knows how machines tick. She rides her bicycle around town looking for things to fix. A skateboard, a bicycle, even a pair of scissors, there's nothing Franny can't repair. Not when she understands that a scissor is a lever, wedge, and a screw; a bicycle is gears, levers, screws, a pulley, and wheels. It's all engineering! Readers follow along as Franny's helps her friends and neighbors fix their machines and learn how they work. Clear, detailed explanations are paired with Edward Miller's signature kid-friendly artwork.

Back matter includes a glossary as well as examples of simple machines.
