author/illustrator: Marissa Moss

Talia loves math puzzles and code-breaking, but the new social rules of middle school have her stumped. Her best friend, Dash, is now embarrassed to be best friends with a girl, so he only wants to hang out with Talia outside of school. And although Talia is excited to make the math team, the strict team captain doubts her abilities . . . just because she’s a girl. But Talia has a great idea: she’ll start her own all-girls math team! As the first competition approaches, Talia is determined to bring her fledgling team to victory, get her best friend back, and break the social code of preteen life. In the spirit of her best-selling Amelia’s Notebook series, Marissa Moss brings Talia’s adventures to life through charming text, illustrations, doodles, graphs, and puzzles. This delightful new series is for all math-lovers, doodlers, and anyone who has ever had to navigate the unfamiliar conventions of a new school.
