Tpotol book 14: Thunder's Nightmare

Thunder had always believed that his world was perfect. His son, Chen while Sehun was thriving under their guidance. Everything seemed to be going well until one day, when Kris and Luhan, the trusted brothers who had always stood by Thunder's side, suddenly announced their departure. Thunder's world caved in as he struggled to come to terms with their decision. Kris and Luhan had been the pillars of the tribe, the protectors, and mentors to Chen and Sehun. Without them, the tribe felt vulnerable, and the future seemed uncertain. Chen took the news hard. He felt the weight of leadership fall upon his shoulders sooner than he had anticipated. Sehun tried to lift his friends' spirits with his infectious energy, but even he couldn't deny the void left by Kris and Luhan's absence.

How will they endure?
