Twilight Prophecy (Children of Twilight)

From Publisher:

THE FINAL BATTLE BETWEEN HUMANS AND VAMPIRES IS AT HAND

According to ancient prophecy, there's only one chance to avert the annihilation of the Undead. Twins James and Brigit Poe, part human, part vampire, believe that they are that chance. In fact, the key lies with the reclusive and mortal scholar Lucy Lanfair--and Lucy's heart lies with James.

Against his own moral code, James draws Lucy into the war between vampires and humans, hoping to turn the tide, but the truth is it's a war no one can win. Lucy knows this, and she knows something else, as well: only by saving James from his own inner darkness can she save the world from being torn apart and, in the process, ensure herself a future with the man she loves.
