Prepare for a fantasy that explodes off the page, a dark and imaginative tale filled with demons and religious conspiracy that fans of Naomi Novik and N.K. Jemisin won't be able to put down. In A Day of Breath, the fate of the world rests on a single, brutal day.

Three hundred years ago, a cult opened a rift to the demon realm in an attempt to summon the demon god Istral. Though they were defeated by the sibyl, a being blessed with divine magic, the rift remains, and the kingdom of Niawa remained ravaged by demons. That is until a sibyl chose a champion to be granted the physical strength to fight the demons through their magic. For seventy years, they have lived by the rift, protecting the kingdom and returning on the Day of Breath, the one day a year the rift closes.

Oly is the longest living champion, now in her tenth year of guarding Niawa. Despite never returning home, she clings to her calling, stemming from her troubled childhood. But Oly's powers are fading, and in order to continue her duty, she needs to find a way to get them back, and fast.

However disaster strikes when a new parasitic demon emerges from the rift, and with it, the spread of death. Amidst the bloodshed, and with her strength fading fast, will Oly be able to defeat the demons and stop a horrific new world order, with Istral at its heart?
