Lady Dawn expected to die.After casting her soul to the wind, taking a one-in-a-million chance to escape the wretched dungeons of Taegrin Caelum, the once-caged songbird of the Asclepius wishes nothing more than to find her Hearth and warn them of the coming danger. Instead, she’s found herself a shade, anchored to a young man who knows far too much—and with far less hope than she’d started with.Toren Daen, for his part, only wanted to make it home safely.

But those in power will not make it easy: Nico Sever is in a league of power all on his own, and Arthur Leywin bears the burden of Fate a continent away. In this familiar-yet-not world of mana, monsters, and looming deities, any misstep along the roads of Alacrya and the High Sovereign’s Dominion could lead to a Fate worse than death.But what is death to a phoenix? With a burning secret in his mana core, knowledge of the future, and a maelstrom of fears and questions, Toren might just survive to be more than what Lady Dawn expected him to be. He might just survive to waylay the encroaching tide of death in the proxy war between raging asura clans.More than all of that, he might just live.
