Hallowed Fang. The Wolf Saint Saga, #2

The mountain listens. And it always answers the ones who ring. Eira has spent her life avoiding the old stories-saints who bleed, wolves who kneel, and the Church men who claim every miracle as proof they were right. But when a cruel zealot named Valtor begins hunting her with hymn-mouthed priests and bells that tighten the air itself, Eira discovers the truth: the mountain doesn't want her faith.
It wants her consent. Marked by a power that flares at blood and refuses to stay quiet, Eira is forced into flight across winter woods and hidden cuts in stone-drawing salt lines that hold only as long as she chooses to hold them. At her side is Bastian, a man bound to the mountain's oldest vow: golden-eyed, half-feral, and trained to obey a voice that still knows how to hurt him. As Valtor closes in on an ancient cairn-the grave of the first wolf saint-Eira and Bastian must decide what they're willing to break to keep a name from being turned into a leash.
and what it means to love someone without making them belong to you. Because some boundaries aren't drawn to keep monsters out. They're drawn to keep you from becoming one.
