"Fallen" is based on the 2009 novel by Lauren Kate. Despite being dismissed at the time as 'Twi-lite', the book went on to spawn five sequels, with "Torment", "Passion", "Rapture" and "Unforgiven" following the original release, alongside side-quel "Fallen in Love".
The first novel in the series was previously adapted in to a feature film in 2016. Also titled "Fallen", it stars Addison Timlin as Luce, alongside Jeremy Irvine and Joely Richardson.
