Adrien Agreste has moved to a new home, thanks to his father's health issues due to stress. At first glance the "new" house seems to have nothing to offer except deteriorated walls and odd neighbors, but that all changed when Adrien discovers a strange parallel world behind a mysterious door. While it does offer him something better than his normal life, Adrien can't shake off the feeling that there is something off about this world, something dark. Disclaimer: I own nothing but the concept of the crossover/AU. The plot belongs to Coraline while the characters respectfully belong to Thomas Astruc, Zagtoons, etc.
