The Song of Achilles

The Song of Achilles is a retelling of the tale of Achilles from the point of view of his friend and lover, Patroclus.
As with all books that provide a modern interpretation of Greek mythology, this one also shows the gods as the evil ones. Additionally, it also questions whether ambition is good and when does it become destructive.
There's a lot of not subtle foreshadowing in the narrative but that liberty is taken because most people are already aware of the tragic myth.
