A SkeleTon of Mystery

The Barrier was broken. The Monsters were free. Saved by a child of their jailers. It has been a year. Monsters, while still not fully accepted, were starting to be a part of the human world again. Our favourite monsters, Asgore, Undyne, Alphys, Papyrus, Toriel and Sans chose to all live together, with Toriel adopting Frisk as her child and the rest as family. But Toriel senses something amiss with her dear 'pun-pal'. And what has happened to Frisk's biological family? "A SkeleTon of Mystery" is my first official story ever, so take that into consideration when criticizing.
