Le Plus Grand Ennemi (Série American Mercenary t. 1)

The military setting adds authenticity and tension, but I'm curious whether real experiences or research influenced the backdrop of this story.

The story’s pacing and surprises made it hard to put down, but I wonder if the author planned all the twists from the start or if they evolved during writing.

The protagonist’s struggles with loyalty and identity felt very real, and I’d love to know what led to the development of that internal struggle.
