When Sonic was young, her friend gave her a necklace. When she gets older she doesn't remember who gave it to her or who had the other half of it, but in turns out to be a big mystery. (There might be a second part too)
It's just a Silver X Mephiles story, not much to say but it's after when Sonic and Shadow get married so u should probably read that before this. But then again u don't have to! *Photo's and characters DO NOT BELONG TO ME!*
