Ilium by Dan Simmons
From the towering heights of Olympos Mons on Mars, the mighty
Zeus and his immortal family of gods, goddesses, and demigods look down
upon a momentous battle, observing -- and often influencing -- the
legendary exploits of Paris, Achilles, Hector, Odysseus, and the
clashing armies of Greece and Troy.

The Penelopeia by Jane Rawlings
From Publishers Weekly
Penelope, wife of Odysseus, embarks on an epic adventure of her own
after her husband returns from his wanderings in this artfully crafted
work, an extended narrative poem in the style of Homer (via Richard
Lattimore's translations of The Iliad and The Odyssey). The book opens
with a startling revelation: while Odysseus has been off on his
journeys, his wife, Penelope, has been raising twin daughters, Ailanthis
and Nerianne, who were conceived just before he left and have now become
young women.

The Firebrand: A Novel by Marion Zimmer Bradley
from Library Journal
Bradley (The Mists of Avalon) has combined several legends about the
fall of Troy in this novel, told from the point of view of Kassandra,
daughter of King Priam. After receiving the gift of prophecy from the
god Apollo and then rejecting him, she was cursed when he decreed that
her vision would be taken as dreams or the ravings of a madwoman.
