Bloodlines — Skyla Dawn Cameron

After three hundred years of unlife, vampire Zara Lain has seemingly done it all, and she's now making a living as a successful thief-turned-assassin. Her newest assignment seems simple enough--kill the aging leader of the O'Connor Coven and his only heir, and she'll have another ten million in the bank.

When a massive assault decimates the continent's population of powerful witches and warlocks, and its orchestrator has vampires being hunted down and captured, Zara realizes the tables have turned and now she'll be playing the hero. Forced to join with a smart-mouthed fellow vampire, a demonologist who's also a fan of hers, a recently widowed--and frequently brooding--warlock, and her best friend's mom, Zara's grudgingly willing to do what she can to save the day. If only people would stop ruining all her outfits...
