Zarda, Fate-Seer of her people, the Drax, has chosen to join the wingless and their broken-winged dams on their long and dangerous journey into exile. But Kalis, the Prime she has abandoned, dispatches flyers to hunt her down and offers a reward to anyone who will give her up. When their path takes them into the Crimson Forest, horror and death stalk the exiles beneath the vines. As the pain and hardship of banishment begin to take their toll, Zarda wonders which of the exiles will be the first to betray her, but nothing can prepare her for the discovery that awaits her beyond the furthest reaches of Drax territory; a discovery that has the power to alter the course of history.
