Book excerpt: Odysseus and his men have done what no other mortals have done: returned alive from the terrifying Land of the Dead. Armed with warnings and advice from the ghost of the prophet Tiresias, Odysseus is determined to finally sail home to Ithaca. But the enchantress Circe tells him that the Greeks will face even more horrors on their journey, including an encounter with Scylla, the six-headed monster, and Charybdis, the deadly whirlpool. Who will survive these terrors--and how? In this third of six books based on episodes from Homer's Odyssey, Mary Pope Osborne continues the exciting adventures of one of the greatest heroes of all time.
