Columbine

A few years ago something happened, and now electicity is dead. Nothing works. Not cars, not phones, not radios. Demons, mages, witches, and vampires now prowl the world without fear, taking advantage of the downfall of humans to live as they want.
One young girl named Columbine Wells discovered that when she bled, her blood played music. In a world where you can never hear recorded music again, it's a luxury that can put her in a predicament she isn't ready for.
