Mystery At 4,000 Fathoms by GravityWillFall01
8 parts Complete
I've never believed in fairytales, superstitions or fears of fantasy worlds. It's the year 1871, and yet people still believe in such idiotic stories. My job as a stoker on this ship is just so I can get some money to live on, but when the ship goes down and I'm rescued in a submarine, I'm forced to help an ambitious Jenny Playfair, a woman obsessed with finding the lost city of Atlantis. She's crazy, of course, or at least I believe she is, until she shows me evidence that such a city just might exist. As we dive farther into the deep in a desperate attempt to find something, and someone, I come to wonder: If Atlantis is real, what are we to expect? Is there more to this than we know? And if the person with me being completely true about her intentions on finding this city? It's an adventure I didn't sign up for, but quickly find myself in. But the more I find and learn about the ocean around me, the more I realize fairytales just might be true after all. Disclaimer: I do not own Zombies, Run! or any of the characters in it. This is my Stoker Five's version of Mystery at 4,000 Fathoms in the New Adventure section of the app.

She's sarcastic. She was the girl who never cared what people said. She was far from a romantic; She was Oreo obsessed. She used to beat up people in middle school, and still throws her shoes at them in high school. She was weird, a good weird. She was sensitive, but piss her off and you'll be scared. It was just her and the small, easy life she had. That was until everything had gone down the toilet. That was until her senior year had started.. ~♦~ Monsters are just everywhere, Only a few people are trustworthy. Would you be my savior if I'm lost there? 'Cause with all the greed, there's left no mercy. At some point I'll be so hopeless, At some point I'll get that feeling, That feeling when trying's Worthless, Doors are closed, I'm barely breathing. I need the light, I need a guide, I'll do things with all my might, Smiling is hard, life's not so "cute", You scream and yet, the screams are mute, When lies, evil and mistakes take all the love away... When asked how you feel it's always "I'm Okay," All the hope you had, got lost in the darkness, You're heartbroken, you feel so hopeless... Crying in the silence is the best you can. Everything has changed in a blurry time span... Would I be able to find true Love? Would I be able to ever again Trust? Be My Savior, Please Don't Be late... Give me true love... I hope you understand. My name is Samantha Walters, and that's how my story went... But who knows how it would end? - #11 in Humor Copyright © Dark_Starlet. All Rights reserved.

THIS BOOK IS UNDER MAJOR CONSTRUCTION, CHARACTERS ARE BEING REMOVED WHILE OTHERS ARE BEING ADDED IN. MASSIVE CHANGES ARE IN STORE FOR EACH CP SO ALL APOLOGIES FOR THE MESS IT'LL BE FOR A FEW MONTHS!!! OR POSSIBLY FOREVER BECAUSE I'M LAZY AF. Additionally, I understand that Masky and Hoody aren't creepypastas. I began this book before I was aware of the fatal error, however I will keep these guys in, due to the fact that many of you adore the duo. Greetings, this was a book I started in late 2013 when I was amateur of writing, so I apologise for the ridiculousness of this book. I'm personally not a fan girl of Creepypasta, that's a bit much for me. However, this was a way for me to interact with others and get a feel of writing so hopefully you guys enjoy reading this as much as I did writing it! :) This includes: Jeff the Killer, BEN Drowned, Slenderman, Eyeless Jack, Masky, Hoody, Lost Silver, Glitchy Red, Laughing Jack, Dark Link, Ticci Toby, Dr Smiley, Homicidal Liu, The Bloody Painter, and Lord Zalgo Also thank you to Canva.com for helping me create this cover, as well as Pixabay.com for the image! ~Enjoy ♥
