Evie is a an orphan who grew up in the palace as a poor relation of Queen Cordelia. It might have been different if she could boast of powerful magic but all she has is one of the mutt magics, in her case a magically keen sense of smell. She wanted to boast of her secret immunity to magic but as she grew up she realized her parents were right and that it would be dangerous to say anything about it. So she spent her time performing whatever tasks none of the other royals want to do until the day Crown Princess Vasilia decided to take the throne for herself leaving alive no one to challenge her claim. Saved by her immunity, and assumed dead by her cousin, Evie finds herself in the gladiator troupe owned by Queen Cordelia's former bodyguard, Serilda. Uncertain if she can trust Serilda, Evie is determined to gain the skills that would allow her to get vengeance on her cousin who is a master with the sword. But the Black Swan gladiator troupe has just as many rivalries and secrets as the palace did.
