The Art of Arrow Cutting by Stephen Dedman

It started simple enough. A tempting woman with a trifle of a problem needed a bus ticket. Luckily, sometime photographer Michelangelo "Mage" Magistrale is there to help her out. In exchange for his kindness, she gives him the key to her apartment. However this key is about to unlock an adventure of a different kind. It is no ordinary key; it unlocks any door and leads those who seek it out of greed directly to Mage. The thought of power like that can drive mortals to extremes but the mortal world quickly becomes the least of Mage's problems. On the run and under constant attack by ninja assassins, Yakuza thugs, and the most fearsome and loathsome otherworldly creations Japanese mythology can muster, Mage's only hope is to conquer the key and its power. He must master the art of arrow cutting in order to unleash his own magical power before the forces of darkness force him into oblivion. In a place where all the doors lead to fantasy, mythology and a terrifying reality, where do you run?
