Pretty When She Destroys - Pretty When She Dies, #3

Amaliya Vezorak always believed she was destined to live a failed life in obscurity until she was brutally murdered by an ancient vampire named The Summoner and reborn as a powerful vampire necromancer. The Summoner's power did not diminish with his death. His long-laid plans are about to bring an endless night to the world, and once the veil between the living and the abyss collapses, reality will be forever altered.
The followers of The Summoner are preparing to claim dominion over humanity, which spells doom for Amaliya's new world and everyone she cares about. As Amaliya, Cian, and the others prepare for their final battle, it becomes increasingly clear that their ragtag group of humans and supernaturals will have to face the forces of The Summoner alone. Though the cabal is growing stronger in their abilities, they are depending on Amaliya to lead them to victory.
Now the young woman who spent most of her life running away from trouble has to save the world.
