Xavier Crespo had the story of his comic book series Cohabitation in mind for many years. He even remembers drawing the first lines of his characters when he was in high school. Cohabitation - Tome 1: Invasion and Genesis of an Invasion are published by MX Éditions in 2021. Because of its storyline that mixes humor and adventure while addressing deep themes, many high schools in Quebec have chosen to use the comic book Cohabitation - Tome 1: Invasion as an original teaching aid. To date, several hundred readers have been seduced. Cohabitation - Volume 2: Adaptation is currently being produced.
