Crimson Letters

When Viola Kestrel is found murdered, High Judge Nova Storme is determined to find whoever is responsible. Then the infamous Crimson Tiger confesses.  It should be an open-and-shut case. She has the reputation, the connections, and more than enough enemies to make the murder believable. But Nova knows something is wrong. The evidence doesn't fit. The Tiger's confession raises more questions than it answers—and the more Nova investigates, the more she realizes that someone wanted her to take the blame. Forced into an uneasy alliance with the very woman she is supposed to condemn, Nova follows a trail of hidden technology, political corruption, and secrets reaching into the highest levels of Citadel Eden.
