Dark Promises by Christine Feehan

Gabrielle has had enough of fights, of wars, of seeing the Carpathian warrior she adores almost lose his life when it isn’t even his battle. All she needs is to be far from the Carpathian Mountains, a long way from vampires and the shadows cast by the disintegrating religious community that shrouds such a variety of frightful insider facts. Yet, she isn’t the just a single looking for answers toward the edges of the obscure…

Trixie Joanes has gone to the Carpathian Mountains looking for her wayward granddaughter, expecting that she has been attracted there by something unspeakable. Rather, Trixie has bumbled onto the way of a urgent man and lady on the run. Also, they’re altogether destined for the sanctuary of a strange antiquated with vengeance in his spirit and the undying energy to make awful dreams materialize.
