But that formula failed him during the final stretch of his senior year when a local gang targeted him, putting everything he had and was building towards at risk.Trapped and desperate, Ace felt his life spiraling out of control—until Ria Hart, a fellow classmate, discovering Ace's innate aptitude to become a Curse Master, a being capable of wielding curse energy and abilities but haunted by Curselings, took pity and introduced him to the secret world hidden beneath the mundane surface of their world, the World of Curses.Awakening as a Curse Master, Ace discovers he possesses an extraordinary innate curse tool: the Cursed Toybox.
