Why I'm writing this book:
For my own pleasure.
Because I think this crossover would be great.
I found none on Wattpad

I suck at descriptions, but here goes.
When Frisk loses control over the Timeline, everybody immediately knows something's up. Sans sets himself the task to locate one of the greatest heroes, and one of the most powerful beings, of all time. Percy Jackson. Will the new team be able to work together and defeat the rising threat, gaining new assets along the way, or will Percy struggle to get over the (slightly altered) Second Giant War, and Annabeth's death, and the Timeline fall to ruin? Find out, in this book.
