Minos , the third work in the Corey Logan Trilogy, begins at the Olympic Academy, where Billy's friend Sara has just carved a magic circle in the hardwood bathroom floor with an ancient double-edged dagger.
She twirls inside her circle calling on the Oracle of Apollo to help her find a modern-day Theseus, the reincarnation of Athens' hero of all heroes who slew the Minotaur.
Lost in her magical dance, she knocks over a candle, sets fire to the curtains, and is suspended from school.
