Right At Gunpoint

Killua Zoldyc. A new member of the FBI's BAU (behavioral analysis unit). In other words, he's a profiler, and a danm good one at that. He spent most of his life in the Santa Barbra PD, working as a detective. Despite his last name, he goes by Killua Rossi. After David Rossi the profiler who saved Killua's and his sisters lives a while back. It's because of him, that Killua became a profiler. He and Rossi have had communication for a long time but he stopped talking to him to get into the BAU the hard way. He knew that Rossi would have insisted on pulling some strings so Killua told Rossi that he wouldn't have communication with him for a while. Killua's speciality is undercover missions, and negotiation.
Gon Freecss. He's a member of the FBI's BAU as well. His father ( Ging Freecss ) is the head of the DOJ ( department of Justice ). He doesn't talk to his father at all, so Ging did not help him get into the BAU. Although, most people still assume that he got in easy because of his last name. However it was the opposite. His father had told everyone to be harder on him because he 'didn't want his last name dragged through the dirt' .

⚠️ murder, suicide, and sexual assault will be discussed. ⚠️
This book won't really have a point of view most of the time, but it will sometimes so yeah. Also most of the extra characters mentioned are from the show criminal minds.
