Love at first Grim.

What if Monroe had a little sister that was abused by their dad and uncle Steven? What if she called Monroe or as she calls him, Roe? What if Nick fell in love with her after Juliette? This fanfiction happens after Juliette and Nick broke up because of what he is hiding from Juliette. I only own Mya, her last name, and Uncle Steven, everything else belongs to NBC. Let the stones land where they may.
