The third and final book in a pacy, lyrical and vivid fantasy adventure set in a world of flying ships, sky cities and powerful paper spirits.

Kurara and her friends have found the key to releasing shikigami from their bonds and granting them eternal freedom - if they can unlock its power. The answer lies in Kurara's homeplace, deep in the mountains of Mikoshima. But can the crew reach it before the imperial forces catch up with them, or their own internal battles break them apart for ever?

Excellent world-building, a dramatic and pacy plot, and an array of deep and believable characters - explored through multiple perspectives - make for a thrilling final instalment in this masterful fantasy adventure.
