Just more of Davidson's wonderfully meandering sentences and wonderfully meandering plot, both of which snap into sense and focus with dazzling intellectual and linguistic dexterity. Vergil is drawn to Averno, a very rich and uniquely horrible city, but who has drawn him there and why? If not already familiar, worth quickly looking up 'Averno' when finished for a sense of how much of a satisfying medieval just-so legend this really is.
