Spy School Goes North

The cold, remote environment adds a unique twist to the espionage story. I'm curious whether the author envisioned this from the start or if it developed during writing.

The mix of funny moments and tense scenes kept me engaged, but I wondered if others felt the same about the book's pacing and tone shifts.

The characters clearly rely on each other, but I'm interested in how their relationships develop amidst all the spy action. Did anyone else see this as a core message?
