Talia's Codebook for Middle School

by Marissa Moss, Marissa Moss (Illustrator)

Overview

From the creator of Amelia’s Notebook—the series that launched the hybrid diary format—book two in this series filled with doodles, graphs, and puzzles draws mathletes and code breakers deeper into the wilds of middle school.

With help from her trusty notebook, Talia thinks she has cracked the codes of middle school—what to wear, what to say, what not to say. But knowledge and mastery don’t always equate, and codes are like homework: just when you think you’re caught up, a new batch arrives. Luckily math brims with codes, and Talia, with her knack for observations and deductions, understands math. As part of a newly merged coed math team, Talia must navigate not only her own struggles with competition, leadership, and stage fright, but also the girl-boy codes and her jealousy of the team’s “perfect” new captain. Being on the same team, it turns out, doesn’t always mean you’re friends, but it does give you the space to try. Second in a charming spin-off series from the creator of the phenomenally popular Amelia books, this doodle-dense, STEM-centric diary will delight and engross readers navigating unfamiliar social terrain.

I’ve been making children’s books for a looooong time. I sent my first picture book to publishers when I was nine, but it wasn’t very good and they didn’t publish it. I didn’t try again until I was a grown-up and then it took five years of sending out stories, getting them rejected, revising them, and sending them back over and over until I got my first book. Now I’ve published more than forty books and each new one is still hard in its own way. Each one takes a lot of revising because I never get things right the first time. That used to frustrate me. Now I expect it. And I don’t mind, because that gives me permission to make mistakes. It means I can take risks and try new things because I don’t have to be perfect—I can always make changes.

I had already published nearly a dozen books when I got the idea for Amelia’s Notebook. I was buying school supplies for my son when I saw one of the black-and-white composition books. It reminded me of the notebook I had when I was a kid, so I bought it (for myself, not my son) and I wrote and drew what I remembered from when I was nine. Amelia’s what came out. I didn’t plan on the book becoming a series, but the first one sold so well and Amelia had so much to say, I kept on going.

Now I’m playing with other notebook formats, like in the historical journals and Max Disaster: Alien Eraser (where I get to play around with making comics, something I love).
