Murderer. Monster. Curse. Six months after fleeing Virian, Zylah Renfall is scraping by as a travelling apothecary, still reeling from the events that forced her to leave in the middle of the night and never look back. But freedom always comes with a price, and for Zylah, it's the sickness spreading through her body like wildfire and the crushing guilt of the life she left behind. When an old friend brings news of a growing army of monsters, and of Marcus—the Fae responsible for her life as a fugitive—Zylah will stop at nothing for the chance to seek retribution for those caught up in the new king's conflict, a vow that could very well cost her everything. Together they must find allies to stand against Marcus as Zylah battles with her declining health, her emotions, and the monsters and magic besieging them at every turn.

To living free.Held captive after a failed attack to take down her enemies, Zylah is determined to uphold her vow—for herself, and for those terrorised by the monsters set loose across Astaria.In her darkest hour she dreams of only two things: revenge, and to be reunited with those she's lost. As dark powers rise to stand against her and time runs out, Zylah must find the strength to escape and call upon old allegiances, even the most unlikely ones if both humans and Fae are to be free. Taking down an ancient Fae might very well cost Zylah her life—a fate she has long since accepted.But will her legacy be freedom, or will it be the downfall of the Fae?
