Ruby and the Mix Games: Hue Series

Twelve-year-old Ruby Majis is learning how to secrete magical ink from her skin's pores. It's painful work, but necessary if she wants to practice Hue: a dangerous, magical sport that transformed her caring older brother Chance into a cold-hearted scoundrel.

Guided by a trainer with a shady past and partnered with a supernatural boy, Ruby embarks on a journey to find her brother at the Mix Games, the annual Hue tournament held on the other side of the world.
