So when she joins them on tour with her best friend Morgan it isn't anything new, except for the fact that now the new bass player is hot and that Max, another best friend is gone. So now she has to figure out a way to get along with the new jerk bassist and find a way to figure out what lie's underneath his tough rockstar persona. TJ Bell/Escape The Fate Fanfic.
