The Golden Apple of Discord, Abomination, Rubicon: Promo

From Goodreads:

Taralie Severin and her three sisters are a powerful coven of modern-day witches who fight evil between bio classes and shifts at the police station. But when Taralie is kidnapped by vampires and converted into the undead, her sisters are ordered by the Milunfra to kill her. The girls refuse and go on the lam with bad vampires and master warlocks hot on their trail. Tara has no choice but to change her sisters into vampires. 

As the young women come to terms with their new circumstances, they encounter the rarest of allies: a band of hot boy-vamps. The guys teach them that everything is not as it seems, their enemies are worse than they'd expected, and they could be on the verge of ending a thousand-year-old civil war.

From Goodreads:

Taralie Severin and her sisters have secured a non-aggression pact with the rulers of the vampire world, the Noricum. Having relocated to Cannon Beach, Oregon, Alexander prepares to marry his beloved Tara. But when an encounter with average vampires goes wrong, the Severin coven's fragile amnesty with the Noricum is destroyed. With the supremacy of their rule challenged, the Noricum set out to restore the balance of power, leaving the Severin family two choices - Die on their feet, or live on their knees.

From Goodreads:

Hidden away on a Caribbean island, Tara's body survived abomination while her mind did not. Strangled from within by Verus's accumulated memories, the eldest Severin sister struggles under the weight of so many conciseness inside her mind. But the Noricum are not idle, nor are they forgiving. Enraged by Tara's murdering of their princess, they hunt the Severins relentlessly. After turning a powerful halfling and declaring open war, the Severin coven must choose between defending the Milunfran witches protecting humanity or their own extinction.
