Tea parties and embroidery lessons? Non, merci.

Thirteen-year-old Sophie Germain would rather spend her nights solving equations by candlelight.

When Sophie cracks a mysterious cipher, she's pulled into a secret society known as the Blue Stockings: inventors, dreamers, and women who think too much. As revolutionary ideas stir both in the streets and on the page, Sophie must decide: play it safe, or join the equation for change.

The Prime Summer of Sophie Germain is a historical fiction novel inspired by the real adolescence of one of history's most brilliant mathematicians, set against the rising unrest of the French Revolution. Packed with puzzles, secret codes, and STEM-rich moments, this story is perfect for curious readers ages 10-14 who want to see how math can be powerful, ideas can be dangerous, and learning can be its own kind of revolution.
