Theo and Colby are running for their lives. They now know the true enemy. Sanctum's pursuit is constant, and it begins to take its toll on both Colby and the Eidolon. Colby grows weaker each time she flashes, while the Fray's beckoning is driving Theo to madness. If they can make it out alive, it will be a miracle. Their bond will be stretched thin; their sanity stretched even thinner. Enemies become allies, and a brother's journey to revenge comes to its snapping point in the last chronicle of the Lucent series.
