Estrella Chavez was just a baby when her father, Victor, the leader of an eco-revolution, was brutally assassinated. Twelve years later, the revolution has been reduced to the non-profit arm of the Water Trust, run by Estrella's godmother, Kit Hamilton, the wealthiest woman in the world.

Now almost fifteen and nearly expelled from school for her violent temper, Estrella is sent by her fallen, aristocratic mother, Linda, to Glouton, an elite academy. The only reason Estrella agrees to go is Mystery School, a seminar on mysticism taught by her hero, the Nobel Laureate Dr. Saul Mather.

But she doesn't know that she'll be in class with the very families that killed her father.

Estrella doesn't know a lot.

She doesn't know about the Spirit War, the Angelai, the Demonai, the Cosmic Scroll, the Crystal Caves, her Alkaline Code, Islid the bear, or the wolves. Not yet.

Through murder, romance, fierce friendships, wild adventures, prophecy, transcendental meditation and blackmail, Estrella must learn how to unlock her code to purify and free the waters that run within, between and around us all.
