The Voice (Nalu fanfiction)

After Team Natsu (Natsu, Lucy, Gray, Erza, Happy, Wendy, and Carla) go on a mission, a dark guild is targeting Fairy Tail and destroy them from the inside out. They put a spell on a guild member that will eventually turn the host into a mindless puppet. Lucy is that host. She tries to fight it but the voice in her head keeps getting louder after she almost kills her own guild member. Can she and her friends silence the voice in her head before Lucy decides to silence it and herself once and for all?
