Christmas lights and her sixteenth birthday brighten Sapphire's days. Her London nights are warmed by the attentions of Ramsey, a kilt-wearing selkie with a smile that promises both fun and trouble. She is growing into the role of leader of the Children of Fire. But her closeness with Ramsey and choice to withhold information causes distrust within her family. Their weakened bond allows a new evil to grow, unrecognized, around them. Horrified by the consequences her decisions have on the people she loves, Sapphire has to choose between her own happiness and her responsibilities as the Jewel of Akasha.
