Nobody expected a street urchin to amount to anything. Considered an undesirable vagrant; an orphan of the streets and a victim of a venomous society based on life essence and luck, no one expects Four to be capable of anything. When Four receives his class on his sixteenth birthday, he is expected to be thrust into the permanent life of a labourer. Monotonous but at least survivable. That was his plan at least. When Four receives a class that no one has ever heard of - one that could prove devastatingly powerful, everything changes. Four is thrust into a ruthless cutthroat world full of indiscriminate death and violence, a hundred factions vying for Four's death or capture. In a quest for survival, Four encounters magic capable of utter annihilation, a book which could provide infinite knowledge and stones capable of subverting the will of even the most strong minded individual. Fighting for survival, Four must rise to the top, or fall six feet under.
