It's back to school for Green Owl and Harrowing! There's definitely something awry in the halls of this institution of higher learning--but is it the students, the faculty, or something else? After all, this is Superville Academy, the sister building of the old asylum and something just as dangerous is brewing below the foundation. As the heroes go undercover to find the truth, Green Owl will come face to face with his forgotten past--and Harrowing--he may just get detention--the kind you don't get out of alive!
