Undone (Rise of the Masks)

In the Red Desert, a fierce battle rages against the king of trogs, threatening the lives of Mel, her friends, and thousands of refugees from the north. Can they survive the relentless trog attacks and escape looming starvation? Marget, a former house maid, has reached the limit of her patience. She and her two companions, Charl and Jaine, have come into an extraordinary power. Together, they can create a towering elemental made of fire and water---but only if they learn to get along and to control their talents. Will this group of friends defeat the trogs in this stunning series conclusion, or will they meet with a grim and violent end in the southern desert sands?
