Based on the book, "The Book With Secrets" by Nerdlike3001. The McKinley High glee club reunion gets hijacked by a stranger with a book of secrets. How will the others react to finding out about each other's lives? The groups from glee, flash supergirl, and a warlock from shadowhunters join together in the fanfiction. Really badly written because I'm only in 7th grade. I have no update schedule, but I will try to update as soon as possible, and if you guys comment to remind me, I may update faster. I do not own any characters or the shows that they are from. This is a work of fanfiction. Date started: Friday, March 13, 2020 Date ended:
