When fifteen‑year‑old Luna Beaumont inherits her grandmother’s house in the vibrant town of Arteville, France, she discovers she’s the descendant of a Guardian of Colors—and that her own magic doesn’t match any of the six known Colors. Worse, it may be tied to the Shadows responsible for her father’s mysterious death. As Luna secretly trains at the hidden Académie des Couleurs and grows closer to her best friend’s magnetic older brother, Adam, the Shadows begin to rise again. To stop them from erasing Color magic forever, Luna must uncover the truth about her Color before the world—and everyone she loves—falls into darkness.
