In this, the third and final installment in the Unreachable Skies Trilogy,
Zarda the Fate-seer, and the Drax she accompanied into exile have settled into a new life far to the north of their homeland, the Expanse. They have pledged their loyalty to Kalon, whose rightful place as Prime was stolen by his brother Kalis.
Zarda''s one certainty is that Kalis'' wingless heir, Dru, is destined to defeat their old enemy, the Koth; but how is he to do that when he is no longer the Prime''s heir? And how can Kalis, his scheming adviser Fazak, and their followers be overcome?
To find the answers and to help the rightful Prime take his place in the Spirax, Zarda must first find a way back through the Crimson Forest for the exiles - but danger and betrayal await them all.
