The Last Song of Penelope by Claire North

Many years ago, Odysseus sailed to war and never returned. For twenty years his wife Penelope and the women of Ithaca have guarded the isle against suitors and rival kings. But peace cannot be kept forever, and the balance of power is about to break . . .
A beggar has arrived at the Palace. Salt-crusted and ocean-battered, he is scorned by the suitors – but Penelope recognises in him something terrible: her husband, Odysseus, returned at last. Yet this Odysseus is no hero. By returning to the island in disguise, he is not merely plotting his revenge against the suitors – vengeance that will spark a civil war – but he’s testing the loyalty of his queen. Has she been faithful to him all these years? And how much blood is Odysseus willing to shed to be sure?
The song of Penelope is ending, and the song of Odysseus must ring through Ithaca’s halls. But first, Penelope must use all her cunning to win a war for the fate of the island and keep her family alive, whatever the cost . . .
