Luna has detected something on the outer edge of the solar system, heading inward. Something she doesn't control, and it seems to be slowing down.

Not only my first fanfic but the first thing I've ever written, so be kind, or not, up to you :)

Feel free to point out my (many) errors, I've got a lot to learn.

Dark tag just in case, it really isn't all that dark though.

Inspired by some of my favorites sci-fi series
