Serena Herondale is one of the best ShadowHunters out there, and the twin sister to Jace Herondale. Recently there has been an increase in demon activity all over the world, but mainly in South Korea and Brooklyn. Serena and some of the other shadowhunters/downworlders are being sent to South Korea to help them maintain the demon activity, which is caused by Sebastian Morgenstern. They have to send the best of the best to help. Serena is thrilled about this because her favorite K-Pop group BTS are the head of the South Korean institute and she's been wanting to meet them for some time now. This group BTS is consisted of 7 boys all posing as k-Pop idols to hide the fact that they are shadowhunters, downworlders and mundanes. This is Serena's journey in finding out more about her powers/abilities and discovering more about herself. She will also find love along the path she is taking. Will she and her friends be able to help control the demon activity and stop Sebastian? Will Serena be able to master her powers and become stronger? What new obstacles will she have to face along the way?
