Fifteen‑year‑old Luna Beaumont is used to instability — new towns, tight budgets, and the constant feeling that she never quite belongs. But everything changes when she unexpectedly inherits a house in France from the grandmother she doesn’t remember. In the vibrant town of Arteville, Luna finally hopes for a fresh start.

Instead, she discovers a secret world woven through the town’s colors — and learns she is the descendant of a legendary Guardian of Colors.

Drawn to the truth her mother refuses to share, Luna secretly enrolls in the hidden Académie des Couleurs, determined to uncover her family’s past and awaken her own Color. But as her power begins to manifest, it doesn’t match any of the six known Guardian Colors: Blue, Red, Yellow, Green, Orange, or Violet.

And then there’s Adam — the most powerful Violet wielder in the school, a brilliant and distant third‑year who also happens to be her new best friend’s older brother. He’s off‑limits in every possible way: older, popular, untouchable… yet impossible for Luna to ignore. Their paths keep crossing, and something sparks between them, even as she tries to stay focused on her mission.

As the threat of the Shadows grows — dark forces capable of erasing Colors entirely — Luna begins to suspect her strange abilities are tied to the danger spreading through Espinal. With time running out, she must embrace the truth about her own Color before everything she’s finally found — her home, her family, her new friends, and herself — slips into darkness.
