There are four authors that influence John F. O' Sullivan's writing style more than anyone else's. For sheer scale and ambition it is Robert Jordan's "The Wheel of Time", for heroic endeavor it is David Gemmell's works in heroic fantasy, for connection to a character it is Wally Lamb's "This Much I Know is True" and and for fluid, beautiful prose it is Phillip Roth. O' Sullivan's debut novel, Daygo's Fury, combine these four styles in an epic fantasy that is real and uncompromising.
