Burning Doorways Book One: Reckoning. Realms Unseen

Going home hits different when you have magical abilities. Coming back to Hanley Cove was never in MacKenzie "Mac" Finn's plans. Years ago she left in fury and disgrace-running from the powers that threatened to consume her. It took the death of Uncle Morley to bring her back. Uncle Morley, who had raised her after the death of her parents. Uncle Morley, who, as Mac soon finds out, had a whole lot more going on than she ever realized.
She thought Uncle Morley didn't know about the Unseen Realms. Or her magical abilities. She was wrong about both. About all sorts of things. One thing becomes clear to her, though. Uncle Morley didn't die of natural causes. Whatever killed him came from the Unseen Realms. Now it wants her. Mac has something these dark entities need. And they intend to take it from her. The first part of the Burning Doorways trilogy, another entry in the artisanal weirdness that is the Realms Unseen.
