The Black Madonna : Book 3 of 'The Mystique Trilogy'

Mia Montrose, archaeological linguist, has discovered that the Black Madonna is a code used by secret societies throughout time for the lost key to an ancient power source: the Sphere of Amenti. Kali, inter-dimensional Queen of the Anunnaki - now fully merged with the youngest Dragon Queen, Tamar Devere - has less than a year to rehabilitate her Fallen kindred who desire inter-galactic domination. Ashlee Granville-Devere, and the Dragon Queens must pool their talents to open the twelve Stations of the Signet Grid and unlock the Halls of Amenti lest the Fallen succeed in using time-travel technologies to destroy humanity. From the ancient past to the distant future, from Montsègur to the way-stations of the universe, from the Underworld of the Kali Rift to the Otherworld of the Ranna Time Flow - the inter-time war must be won for the sake of the future.
