This is book number 1 in the Blood Books series.
There's no wrath like that of a witch scorned.
As one of the only spirit users in her coven, Avah has been chosen to wield The Power, the ultimate weapon against the immortal vampire species witches have been at war with for centuries.
But on the night of her birth rite, Avah's coven is attacked. Forced to seek refuge among the very beings she's sworn to kill, Avah vows revenge on those who took her former life from her.
As Avah slowly transitions into a life of blood and war, she realizes everything she's been told is a lie.
