This is both The Hesiad Trilogy and The Apolliad series combined in one book. The two series were written as a continuation of each other and intended as one wholistic work of literature written over many years, in a sequence of many books.
Hexagon is the combination of all the books into one long epic as it was always intended to be. The ancient god navigates his way through a contemporary world after emerging victorious from the ancient world. Hexagon is a tale of the triumph of the ancient self over endless perils and against all odds, written in rhymed verse.
