Fallen Angels is a 1988 young-adult novel written by Walter Dean Myers, about the Vietnam War.
 It won the 1988 Coretta Scott King Award.

The Mortal Instruments is a series of six young adult fantasy novels written by Cassandra Clare, the last of which was published May 27, 2014.
 "The Mortal Instruments" is chronologically the third series of a proposed five in "The Shadowhunter Chronicles" but it was the first one published.
 It follows Clary Fray (who interacts with a group of nephilim known as Shadowhunters) while also discovering her own half-angel heritage.
 The Shadowhunters protect the world of mundane people who are also called "mundies" from dark forces from beyond their world.
The Infernal Devices is a series of novels by author Cassandra Clare, centering on a race called the Shadowhunters introduced in her "The Mortal Instruments" series.

City of Fallen Angels is the fourth book in "The Mortal Instruments" series by Cassandra Clare.
 The series was meant to end with "City of Glass"; it was announced in March 2010 that a fourth book would be added, with Cassandra Clare later saying that she views this as a "second trilogy" in the series.

Bezaliel (also Busasejal, Basasael), Aramaic ניאל (damaged), Greek Θωνιήλ (damaged), was the 13th Watcher of the 20 leaders of the 200 fallen angels that are mentioned in an ancient work called the Book of Enoch.
 This angel is probably one of the most controversial of the list of fallen angels in the Book of Enoch.
 He is often left off the list of angels from chapter 6 as a result of the problematic transmission of the text.
 The R. H. Charles translation from 1917 does not include him on the list of 20 leaders.
 Michael Knibb says as of 1982 there were various translations of the name all with different names and meanings.
 The name Bezaliel (Shadow of God) is taken from chapter 69 and is the 13th angel listed there.

 The song is inspired by the biblical story told in the Book of Revelation, Chapter 12, in which Satan and one-third of God's angels rebelled against God, starting a war in Heaven and were therefore cast out of Heaven to the earth, becoming "fallen angels."
