Curious ten-year-old Saffron Speiser-Green loves science--unfortunately, her "experiments" tend to end in more messes than actual answers. (Just ask the broken alarm clock that's still at the bottom of her backpack.) Saffron has a plan, though--a blue ribbon for her volcano project will show the world she means business. But when a test-run ruins the walls at Mama's job and gets Mama fired, Saffron will do anything to make things right--even giving up her shot at the blue ribbon to help her moms save Gran's rundown coffee shop in the Silicon Valley. 

​

Surrounded now by self-driving cars and classmates that spend their summers at tech camps, Saffron realizes the move isn't just a good thing for Mama. Saffron's new classmates are busy preparing for a STEM Expo, and Saffron is determined to find a project "smart" enough to show everyone she belongs. But the coffee shop? No customers, no vision, and ... tons of debt. And if it closes, Saffron and her moms will have to move again. After a class trip to the STEAMology Museum, though, Saffron has an idea that could save the cafe--and her STEM Expo project. But she's going to need lots of help. 

​

Can Saffron prove she's more than a mess-maker and rescue the family business?
