Years ago, the Broods led an unprecedented raid to destroy one of the other ancient houses. Their only mistake was not finishing the job. A few of the Tin Vori siblings survived, and they haven't forgotten the crimes committed against their family. Quietly, they've plotted their own revenge, waiting for just the right moment to strike. And Ren Monroe might be their best chance.
