Morning Glories, Vol. 1: For a Better Future

This is one of those books you definitely can't judge by its cover. The cover is teeny bopper, but the interior content is DARK AF.
Morning Glory Academy is one of the most prestigious prep schools in the country... but something sinister and deadly lurks behind its walls. When six gifted, but troubled, students arrive, they find themselves trapped and fighting for their lives as the secrets of the academy reveal themselves!
