Screenwise Verdict
This isn't your typical dry 'educational' book. Frankie is a firecracker who actually uses her brain to solve problems. It’s refreshing to see a story where a kid uses research and blueprints to get what she wants instead of just whining.
It’s a great pick for kids who are starting to move past easy readers but aren't quite ready for the heavy themes of older middle-grade novels. Plus, the STEM elements are baked into the plot so naturally that kids won't even realize they're learning the scientific method. It’s smart, diverse, and actually fun to read.
Age Fit
Perfect for 7 to 10-year-olds. It’s a great bridge for kids moving out of early readers into more complex chapter books.
WISE Breakdown
Wholesome
92
Models healthy friendship dynamics and supportive family interactions. It handles the 'mean girl' or 'disagreeing friend' tropes with more nuance than your average 3rd-grade drama.
Imaginative
88
Frankie's 'inventor' mindset encourages kids to look at the world as a series of problems waiting for a creative solution. It’s high-quality brain fuel for the LEGO and Minecraft crowd.
Safe
98
Completely safe. No mature themes, violence, or 'surprise' content that would catch a parent off guard. It’s a gentle but engaging chapter book.
Enriching
90
Heavy STEM integration that feels organic, not forced. It also features a Black female protagonist in science, providing excellent representation without making it a 'lesson' book.

Why It Might Be Great
It makes the scientific method actually look cool and useful for real-life kid problems.
Frankie is a fantastic role model: she’s smart, persistent, and totally obsessed with rodents.
The diversity is handled naturally—Frankie is a Black girl who loves engineering, and it’s just part of her character, not a plot point.
The chapters are short and the pacing is snappy, making it a win for kids who are still a bit intimidated by big blocks of text.
⚠
What to Watch For
Be prepared for a very logical argument from your child about why they need a pet rat (or a lab in their bedroom).
There’s some minor tension between Frankie and her best friend, but it’s handled with actual communication rather than just being 'mean'.
Conversation Starters
"Why do you think Frankie's classmates were so grossed out by the idea of a rat?"
"If you had to invent a machine to help with your chores, what would it do?"
"How did Frankie use research to change people's minds?"
"What do you do when your best friend doesn't want the same thing you do?"
