the Books

Wren Sterling isn't like the other kids at Ada Lovelace Charter School. They all seem to know what's going on. She's just trying to get through the day without adding another notch to her Principal's Office frequent flier card. Her safe haven is the Renegade Girls Tinkering Club, with her three best friends. It's the only place she feels like she can be herself.

When an accident breaks the club's beloved professional grade microscope, Wren has to find a way to fix it or she may not make it through middle school. Their solution is to start a business inventing and selling spy gear. After a rocky start, the business begins to do well. Maybe too well. The club Wren loves and relies on starts to tear itself apart.

Then the club is accused of a theft at school. The Renegades must join forces again to clear their names. And just maybe Wren can discover she might have a bright future after all.

"Super amazingly awesome and easy to get lost in."

the Series

A Hands-on Reading Experience

The four girls in the Renegade Girls Tinkering Club are just starting to explore their future as they move from elementary to middle school, and are on the cusp of becoming young adults. As life becomes more complicated, how can they grow their love of exploring and inventing into the next stage in their lives? Join these middle schoolers in ongoing adventures about learning your strengths, exploring your passions, and doing what needs to be done. 

In the books, the girls confront various roadblocks girls face on their path to becoming Women in STEM: finding their place, being dismissed as 'girly', being over-scheduled and feeling the need to satisfy other people's expectations, and perfectionism and impostor syndrome in realistic, relatable ways. There are no dark dystopian governments to overthrow, no aliens or dark gods to battle or portals to slide through, and none of the girls have superpowers. Those are all fun elements, but young girls need to know that kids JUST LIKE THEM can become scientists and engineers. You don't have to have superpowers to make a difference and follow your passions.

Coming Next!

Look for book two in the, Renegade Girls Tinkering Club series, Style Renegades, coming out in December!

the Renegades



Wren Sterling’s mechanical mind and poor impulse control frequently get her into trouble. Can she use her powers for good, or is she destined to be everyone's favorite screw-up forever?



Amber Rosenberg loves both science and fashion, but will anyone ever take her seriously as a scientist while she's wearing a princess dress?


Kaminia Doyle may get constantly overlooked, but underneath her quiet surface lurks a gift for organizing, systems, language, and patterns. If she could lighten up and take a few risks, maybe even let herself fail now and then, who knows where those gifts might take her? 


Ivy Rose

Ivy Rose Park wins everything she does. Some day she'll be an electrical engineer, but how can she fit in the extracurricular study with multiple sports, schoolwork, and the tinkering club? So much to do, so little time.
