The triumphant conclusion. Spoilers ahead for the earlier work.
Opens with Caspian having deal with an issue from his past, and the whole company having to bolt. Then Dara, separate from them, learning more about Ancients. And the conclusion involves Mac showing off what she do with the watches -- and still more mechanical skills; Roan discovering things about Elnor and arguing with her; finding a man dying; missing sailors; and more.
