My name is gone, along with everything I love. And it's all my fault. I think. My memories fuzzy. Like they're someone else's. So I'll tell you my story as if it happened to someone else. While I try to remember, I'll tell you a story. All of these people are so different, and yet they were pulled together by something that seemed like fate. This is, was, my sad story.

Rapunzel goes to an ordinary school. She has ordinary friends, well only four friends. Merida, Jack, Astrid and Pascal, but none of them were really normal. Jack was an outcast, Merida was a fiery, hot headed girl, Astrid was seemingly sweet but could be extremely protective if someone antagonised her, and Pascal, a lizard.
But this is just the first story.
Everything isn't okay. School's hard. Bullies. And of course, the guy who broke the ceiling of her Math classroom (is that really a bad thing?)
When the boy with green eyes breaks through the ceiling of her maths classroom, Rapunzel's life changes forever. She is whisked away to a new world filled with danger, extremely sharp objects, puppy-like dragons, and of course, at least thirty people who want to kill her at any time.
When a new prophecy arises, will Rapunzel be able to figure out what it means and save her friends?
Will they be able to work together and save the world?
Can I write a whole story?
We'll find out.

A/N: I own the majority of the plot, but I will be using some things from the separate book series and Movies/TV Shows (Heroes of Olympus, Grishaverse books and Throne of glass)
Ok, so this isn't a Mericup story. I write both Mericup and Hiccstrid stories, so no getting mad at me.
