Chakuro and the other Marked children have freed the Unmarked from the Amonlogian dungeon, but their rescue mission is far from over. The people of the Mud Whale still need to get back to their island home, and the path to safety is blocked by imperial soldiers. Even worse, Orca is determined to secure Ouni in order to carry out his diabolical plans! -- VIZ Media

It is year 93 of the Sand Exile, but the implications of that calendar are only now sinking in for Chakuro. Imperial soldiers from the Allied Empire have appeared out of nowhere with orders to kill all the “criminals” of the Mud Whale! The Committee of Elders knows why this is happening but still won’t explain it to the young Marked of the island. And the elders would rather see the Mud Whale sink forever to the bottom of the Sea of Sand than leave them all at the mercy of the empire. -- VIZ Media

The people of the Mud Whale have been trapped on the floating island since their ancestors were exiled to the Sea of Sand nearly a hundred years ago, yet their prison has mostly felt like a home. But now the true extent of the punishment inflicted on the criminals of Fálaina has come to light, and the cost exacted by their home is immense. -- VIZ Media

Lykos and Ouni have been captured by Orca, but instead of organizing a rescue, Suou has ordered the Mud Whale to set sail for their new homeland. Chakuro won't just abandon his friends, though, and he's determined to find a way to save them. But Orca has just declared independence from the empire, and any rescue attempt will end up right in the middle of his cataclysmic plans! -- VIZ Media

The Mud Whale is in dire trouble. In four days, the imperial apátheia soldiers will return to destroy it and its inhabitants. But the Committee of Elders would rather kill everyone on board than wait for the “mercy” of the empire, and the fighters of the island will do the elders’ bidding without a second thought. Now Chakuro and the other children are forced by circumstance to rebel against the adults in order to save their home and their lives. -- VIZ Media

The battle for the Mud Whale becomes a deadly rout as the Marked fight to protect their home and their comrades from the invading apátheia soldiers. Meanwhile, Chakuro and the rest of the boarding party have made it safely onto the imperial battleship Skyros, but their mission turns bloody when they reach the thymia-proof chamber at the heart of the ship. How will they destroy the enemy Nous and save the Mud Whale without access to their powers? -- VIZ Media

The promised haven of Amonlogia is closer than ever, but the dark history of the Mud Whale still poses a terrible threat to its people. Somehow, learning the truth about the past has freed Ouni’s thymia from any constraint, and he is forced to lock himself away to avoid hurting the others. But even with that precaution, his very presence is a danger to his people as Orca mounts an expedition to capture the daímonas and kill everyone else! -- VIZ Media
