Marco did okay in math. He could follow the complex blueprints provided to him, navigate the steps, and arrive at the answers that earned him a shiny grade near the front of the alphabet. That is, until middle school. As new and confusing letters started creeping into every question, Marco developed a problem. When a new figure 'pops' into his life, he is introduced to a fantastical world where numbers rule, where they live together in villages, engage in duels, build stadiums and cheer for their favorite team as players are flung through the air. Marco's imagination runs wild as he develops new powers and hungers for more.

But everything is not as it seems. Join Marco, his annoying little sister Maggie, and his best friends Oliver and Liam (a math whiz and a conspiracy nut), as they discover this magical world is more real than they ever could have dreamt. And find out... Will Marco master the Numberfolk before the Numberfolk, very literally, master him?
