Monster Hunter International is a book published by Baen and written by Larry Correia, so Retaliation is, strictly speaking, fan fiction. However, I had fun writing it, and I hope you enjoy reading it as well.
Before I forget, here’s the requisite disclaimer. It applies to all MHI: Retaliation chapters: “Monster Hunter International and all related intellectual property are owned by Larry Correia and Baen Books. “
