This is just the old Love and Lies with some...changes...

The GameStream: a separate dimension where you have access to all games ever created. The HomeStream: a side dimension where you stay while not in the games. But what happens when both of the Streams is taken over by mysterious, dark, floating vessels? From the soon-to-be author of many more books, comes the part science-fiction, part fanfiction tale of two people destined to stop the invaders. Caution: May strongly appeal to Undertale fans. Do not read if you've not beat the game: contains spoilers. Not all characters are mine: Some belong to TOBY FOX and MOJANG Not all of the art is mine either. Fan art would be appreciated so if you want to contribute just message me. Enjoy!

I suck at writing descriptions so yeah, just read the book/story/whatever.
