There are two book series called The Mortal Instrument and Infernal Devices. They are book series that I love (and everyone must read them).
The other day I saw two songs of two girls who had composed some songs for the book series. I found they were very well made and perfectly matched the letters with books, so I'm going to leave here, for fans of the series to hear them.
