This book was about a female who was training to be an assassin, and she went on a mission with other assassins who ended up branding or killing her team. The cover was dark and had a dagger or sword on it. I read this last year. It is a YA book. The assassins may have been working for a queen or something, or they were a secret service sort of thing. The female's trainer was her dad, I think. And her brother also had a prominent role in the book. I did not finish the book and would like to, but can't find it. Any help will be appreciated!!
