Guildpact (Ravnica Cycle, Book 2)

One guild ravages the streets. Teysa leads another to "cleanse" them. And Agrus Kos doesn't give a damn.

But as he watches the guilds nip and tear at each other like snakes . . . something clicks.

Now his mind is clear, as are his options. A disaster grows under the city's crowded streets. He knows what he must do.
