On the vibrant, prismatic Planet Hue, kingdoms of color rule their lands with strict laws and practices.
Ruby, a headstrong, seventeen-year-old princess, longs to be the next ruler of the Red Kingdom. However, societal standards reject her, for only males can lead. Because of this, her younger brother Crimson will take her dream and her place on the throne one day.
When Ruby becomes blessed with the Prem, a mysterious power that allows one to see the future through dreams, she believes she may finally have a chance of showing what she is worth. However, her excitement for her newfound importance and power is short-lived when her Prems start to reveal a dark and cursed future.
Crimson has no interest in the throne and the shackles that come with it. However, his fate, and the fate of his whole family, start to intertwine when a glowing stone that pulsates with an unknown power suddenly crashes down in their homeland.
When it falls upon the shoulders of book-smart Vermillion to figure things out, the youngest prince struggles to come to an understanding about this mysterious stone. That doesn't stop him though, as his curiosity leads him down a new route, one shrouded in mystery.
Is this stone the same one that Ruby's Prem foretold? Will Ruby and her siblings be able to alter history and save their family from the forthcoming darkness?
Or will this turmoil tear them apart?
