Homer 
The Iliad [EPUB ebook] 

One of the oldest extant works of Western literature, the Iliad is a timeless epic poem of great warriors trapped between their own heroic pride and the arbitrary, often vicious decisions of fate and the gods. One of the greatest stories ever told, ‘Iliad’ has survived for thousands of years because of its insightful portrayal of man and its epic story of war, duty, honor, and revenge.
After nine years fighting the Trojan War, the Greeks sense imminent defeat. The gods have cursed them with a plague; the Trojans have set their ships on fire; and their best warrior, the impenetrable Achilles, has turned his back on them. But when the Trojans go too far and kill Patroclus, his beloved brother-in-arms, Achilles returns to the battlefield with a vengeance so terrible that it shocks even the gods.
