The Human Underground book one: Magic knows no bounds

Alisa was only a little girl when she and her two canine friends fell into the Underground, only ten years old. Eight years past since she fell and the girl was glad she did. Her past could not get to her here and everyone was kind and accepting of her. She couldn't let them know of her secret though. They would hate her and hurt her and Alisa wouldn't be able to fight back.

Word gets around eventually to the skeleton brothers and Sans gets curious. Who is this strange human and why were they different than the rest? Not wanting to go back to the surface?

This is a story of friendship, family, and love. Though, magic has something to do with all of that though... SansxOC
