The Raven Scholar

She might win the throne. She might destroy an empire. Either way, it begins with murder.
After twenty-four years on the throne, it is time for Bersun the Brusque, emperor of Orrun, to bring his reign to an end. In the dizzying heat of mid-summer, seven contenders will compete to replace him.
Trained at rival monasteries, each contender is inspired by a sacred animal - Fox, Raven, Tiger, Ox, Bear, Monkey, and Hound. An eighth - the Dragon proxy - will be revealed only once the trials have begun. Eight exceptional warriors, thinkers, strategists - the best of the best.
Then one of them is murdered.
It falls to the brilliant but idiosyncratic Neema Kraa to investigate. But as she hunts for a killer, darker forces are gathering.
If Neema succeeds, she could win the throne - whether she wants it or not. But if she fails, she will sentence herself to death - and set in motion a sequence of events that could doom the empire . . .
