The Hero Defined is the second series in the planned Mage trilogy.  It comes after The Hero Discovered and before The Hero Denied.  It was published many years after the first series.  The third series has not yet been published, many years after the second series.  The second series had more of a mixed critical reception than the first series, but still had an enthusiastic following.
 
In it, Kevin Matchstick has become a more experienced and successful warrior, but to the detriment of his character.  He must find his second mage in order to learn how to move on to a better path--although he doesn't see it like that.
