There are science experiments. Then there are Fran experiments—and those are next-level chaos.

In The Invisible Fran by Jim Benton, we dive headfirst into the hilarious world of Franny K. Stein, a young mad scientist with a genius brain and a lab in her bedroom. But this time, she’s cooked up something totally new: invisibility.

Yep. She figures out how to disappear.
And let’s just say—it doesn’t exactly go as planned.

"Sometimes you have to become invisible to be truly seen." That’s the kind of twisted genius you can expect inside this book. It's clever, funny, and surprisingly full of heart. Franny doesn’t just want to vanish for fun—she wants to help, even if it means becoming an unseen hero. Or... at least trying not to blow things up in the process.

This book is perfect for readers ages 7–12, especially those who love science, humor, and unapologetically weird characters. It's packed with fast-paced action, quirky illustrations, and laugh-out-loud moments that even reluctant readers can't resist. Seriously—Franny is like if Wednesday Addams and Einstein had a kid. She's THAT cool.
