The elves of the lesser realms are desperate and in their desperation, they propose a radical plan, a plan that they hope will save them, a plan that requires Bhree becoming a sovereign. But that plan also requires Cayal's buy-in and he makes the price very steep. Cayal complicates things even more by relinquishing his representation on the ambassadors' council by consolidating everything in the valley under Kresta, making her the most-powerful person in Teriador. Alongside this desperate plan, Lybryn's magic and her reaction to it are revealed. Cayal and Bhree struggle to make sense of who the little girl is. While they try to control the extraordinary events of their lives, Cayal and Bhree experience the ordinary of their two daughters falling in love. Part 12 of Brighter Than A Thousand Suns continues the story of Cayal and Bhree as they try to save a world that sometimes doesn't seem to want to be saved and make sense of magic that doesn't seem to want to be understood.
