Seven Blades in Black (The Grave of Empires, 1)

Acclaimed author Sam Sykes returns with a brilliant new epic fantasy that introduces an unforgettable outcast mage caught between two warring empires.
Her magic was stolen. She was left for dead.
Betrayed by those she trusts most and her magic ripped from her, all Sal the Cacophony has left is her name, her story, and the weapon she used to carve both. But she has a will stronger than magic, and knows exactly where to go.
The Scar, a land torn between powerful empires, where rogue mages go to disappear, disgraced soldiers go to die and Sal went with a blade, a gun, and a list of seven names.
Revenge will be its own reward.
