Blood Ties — Amelia Elias

Orion, a centuries-old vampire, lives by three rules:

Trust no one.
Need no one.
And never fall in love.

But his mortal Associate, Kira, turns his world upside-down and tempts him to abandon his solitary path. On the day she stuns him by delivering her resignation--to wed a man who works for Orion's sworn enemies--he realizes he's broken all three of his rules. And in the next instant, all he owns is destroyed in shocking betrayal. The attack leaves Orion without a safe haven, and what's worse, with Kira dying in his arms.

And now Orion will live by a new law--do whatever it takes to save Kira and convince her to join him in eternal night.
