Bound to the Black Wolf. The Wolves of Blackhollow Academy, #1

At Blackhollow Academy, wolves do not choose the weak. They choose the useful. Sora Wulfric has spent her life stealing medicine, fixing broken weapons, and surviving the dirty streets of Gravenhold's lower ward. She has no noble blood worth respecting, no powerful family to protect her, and no reason to trust the rich wolf-bonded heirs who fly above the city while people like her starve below. Then the king's Pale Guard takes her younger brother.
No charge. No trial. No mercy. To find him, Sora does the only thing left. She steals a dead noble girl's name and enters Blackhollow Academy, the brutal war school where elite heirs fight to bond with ancient wolves and become riders of the Crown. But Blackhollow is not a school. It is a grave with gates. Every lesson can break bones. Every trial can spill blood. Every noble student wants Sora exposed, humiliated, or dead.
And Commander Wolfram Draegun, the cold and dangerous trainer assigned to watch her, sees too much, asks too little, and stands too close when Sora is trying very hard not to trust him. Then Choosing Night comes. No academy wolf claims her. The nobles laugh. Until the mountain shakes. Morgrym, the forbidden black wolf chained beneath Blackhollow for a century, breaks free and chooses her. The wolf no rider has survived.
The wolf blamed for slaughtering a royal bloodline. The wolf the Crown tried to erase from history. Now Sora carries a bond that should not exist, a power the nobles fear, and a bloodline the Crown has been hunting for generations. To save her brother, she must survive deadly academy trials, court betrayal, poisoned rivals, and the brutal pull of a wolf bond that feels less like magic and more like a second heartbeat made of teeth.
But the deeper Sora digs, the more Blackhollow bleeds secrets. The Crown is lying. The Pale Guard are not what they seem. And Sora's brother may be the key to waking something buried beneath the mountain. At Blackhollow Academy, love is leverage. Blood is inheritance. And every bond has a price.
