We Are Blood And Thunder by Lupo, Kesia

On the edges of a sealed-off city, a chance encounter between two girls in the misty woods is about to change the course of everything. . .

Lena is on the run from her home, the Duke's Forest, after being convicted as a mage and sentenced to death. Meanwhile, Constance escaped the Forest years before, after her own magical powers were discovered--but now, she will do anything to get back inside and reclaim her place as the duke's daughter. The girls cross paths for only a moment, but that's long enough to set them down paths that will change the dukedom forever.

As Lena reaches a safe haven where she can study and develop her powers alongside handsome but mysterious mage Emris, Constance maneuvers her way back into the home she left behind, unsure whether she trust the people she once considered her family and friends. All the while, the girls are connected by the dark, terrifying storm clouds that hang over the land and devastate everything in their wakes.

Only Lena and Constance hold the keys to dispelling the storm and keeping their home safe--if they can uncover who cast the spell that generated the clouds to begin with. But the truth is far more sinister than anyone could imagine, and it could mean that one of the girls will lose everything.
