Althea's Math Mysteries
(4 books, coming soon)

Althea asks her mom if there's a square root of -1. Mom tells her about some crazy history, and they play with imaginary and complex numbers.

Althea and her friends - Kiara, Sofia, and Aiden - get together to explore geometry, pi, and trigonometry.

Althea and her friends explore the many ways infinity can show up when we're playing with math. Now her brother Rudy and his friend Sami join them.

Who is Althea?

Here's what she says in the beginning of the first book:

We live in a funky old house - me, my brother Rudy, and our moms. I get to homeschool now, and I love being able to read all day one day, ride my bike for miles and miles the next day, and then play around with math problems the day after that.

And of course there’s my cookie-baking project. I’m trying to make as many different kinds of cookies as I can.  Yum. 



Wait, where's book 4? 

The 4th book will be Althea and the Mysteries of Calculus, in which Althea and her friends (Kiara, Sofia, and Aiden) begin to explore the history and ideas of calculus, with a bit of help from Mom. The schools are online because of Covid, and they're all homeschooling for the duration. 

I don't even have a mock-up of the cover yet, but it will be so fun to write. I love calculus, and it sure was mysterious in Newton's time!
