Unexpected

Melody wakes up and has no idea where she is. There are two people, who she later finds are Four and Tris standing in an all too familiar room with her, and they take her away to Dauntless. She meets three others with the same problem as she has; no memory, and showing up randomly. She's homesick, but she doesn't know where home is. For now, she'll just have to adjust to life in Dauntless until she can find "home".
