I made some graphics: http://iworkdumbledoreswanddaily.tumblr.com/tagged/story
Paradise is a prison set up of on an island off the coast of Texas. Because of its location, it means hardly any inspectors or observers come to visit, meaning they can do whatever they want. Under the control of the prison guards, of course...But even they aren't bothered. In fact, if its their time to leave, they'll commit a crime just to come back. However, no "simple" cases are accepted. For example, most people are here for murdering over 10 people, or robbery of the CIA... Even arson of the highest degree which ended in burns of 75%. They were lucky to be alive. The prisoners who currently reside here are: Rowan Evans, Zoe Leslie, Emma Topliss, Molly Graham, Vanessa Webb, Ava Stewart, Lily Gray, Olivia Cooper, Isabella "Issy" Jenkins, Daisy "Dizzy" Climo, Natalie Gwin, Stuart Harrold, Hoyt Simpson, Jayden Harris, Daniel Gray, Red Gray, Noah Collins, Mason James, Jake Turner, Calum Hood, Luke Hemmings and the ten staff: Cassie Johnson, Emma Johnson, Addison "Addy" Anderson, Avery Johnson, Ariana Sanders, Cyrus Gray, Mack Louis, Christian Adams, Dylan Perry and Diego Hernandez. They boys and girls are supposed to be in separate buildings, but due to the staff quarters being mixed, the staff don't care. Visiting hours are practically for the whole day. The staff aren't bothered, as long as you 1. You don't kill anyone, and 2. You don't leave. The staff are as bad as the prisoners. Welcome to paradise.. Enjoy your cell.
Disclaimer: The Paradise Falls Series is based on a Tumblr RPG. I don't own the idea of the island, but I do own most of the character's names. No surnames are the same as the original. All of the credit for that part goes to that. This story is based on my own ideas.
