Nephilim

Seventeen-year-old Rémy is a Conjuror—someone who can alter reality with his music. But such a talent comes with a price. He and his superpowered friends, Matt and Em Calder, are engaged in a dangerous battle to save humanity as we know it. If they are to succeed, they must first decipher a coded message in Rémy's dead mother's journal. A message which will lead them to an ancient scroll buried deep in the Vatican—and towards dark forces which have risen from the depths of time.
