Shanower's Achilles is fascinating. And to be honest, I think it's interesting that Shanower has not depicted him or Petroklus at all sympathetically all the time--the way Achilles leaves his wife is treated as being cold and mean, as is Achilles. But then, a constant theme throughout is that these men treat women who are not their daughters like garbage. The whole plot is driven by, basically, what was a property agreement over Helen.
