MASK OF SHADOWS by Linsey Miller
Sallot Leon is a thief, and a damned good one at that. When they find a flyer proclaiming the death of one of the Queen's assassins, known as the Left Hand, Sallot decides to go for it. They enter themself into the running, and train along side the remaining Left Hand and other contestants. As they fight for the place of Opal, the fourth Left Hand, Sal finds themself entrenched in something more than a simple competition. It's a fight to the death, and they can only win if they survive.
