The Darkness (Vampire Huntress Legend #10)
After the battle at Masada, the Neteru team returns to San Diego believing forty-thousand demons had been eradicated and that Lilith's spawn has been killed. But somehow the treacherous little creature got away. Just as had been prophesized at the dawn of the Armageddon, the anti-Christ has been born and will soon rise to power.
Rewarded for her creation, Lilith is given the daylight bite and power to make Councilmen day-walkers. Having Fallon Nuit and Sebastian able to withstand sunlight is a huge problem, especially when they are adding new master vampires at recordbreaking levels. Meanwhile the dark realms are healing and adding to what had previously been wiped out—feeding off the dark energy of the newly created anti-christ who is only waiting to emerge.
