Darkness Rises — Dianne Duvall

Dianne Duvall returns to the world of the Immortal Guardians, where danger--and desire--make every decision count. . .

Krysta is used to getting the drop on vampires. Her "special abilities" aren't much, but the plan is simple--she plays helpless pretty young thing to lure them in. Then her shoto swords come out and it's bye-bye, bloodsucker. Until one night she finds herself with an unexpected ally. He's a vampire, all right, but different. Mysterious. Handsome. And more interested in saving her skin than draining it.

Étienne has been an Immortal Guardian for two hundred years--long enough to know that Krysta is special. He can't stop thinking about her long legs, even more than her short swords. Then he discovers the vamps she's exterminating have friends in high places, and the Guardians are in danger too. He'll have to accept Krysta's help to save them. The stakes for a mortal are high. But the cost to his heart might be higher. . .
