The Grigori Trilogy is a series of three gothic horror novels by British author Storm Constantine.
The series tells the story of the Grigori, a race of fallen angels who are being rewoken in preparation for the new millennium, and their children by human women, the Nephilim.
Constantine draws upon a wide-ranging bibliography of references for her novels.
Elements of John Milton's Paradise Lost, Lord Byron's Heaven and Earth and the writings of paranormal author Andrew Collins can be found throughout the series.
In 2006, the first book in the series was brought back into print by UK-based Immanion Press.
