Man or God; what happens when the lines are blurred?

Haern is the King's Watcher, protector against thieves and nobles who might fill the night with blood. Yet hundreds of miles away, an assassin known as the Wraith has begun slaughtering those in power, and leaving the symbol of the Watcher in mockery. When Haern travels south to confront his copycat killer, he finds a city ruled by the corrupt, the greedy, and the dangerous. Rioters fill the streets, and the threat of war with the mysterious elves hangs over all. To stop it, Haern must confront the deadly Wraith, and the man he might become.
