Spectrum (Spectrum #2)

Do you ever wish your life was more normal? Ada Latimer wants to be normal. She owns a quiet little record store. She's in love with her corny (but sweet) boyfriend. But the chance for normalcy vanished when her father Leon abandoned her as a child to search for the mythical record producer George Parker. The ramifications of Leon's quest come back around as Echo, one of the Sustained - a being with the power to alter reality through music - shows up at Ada's shop looking for answers. So much for "normal."
