The Vessel by Peggy Christie

Nora is an average woman in an average job with an average life. She senses that she is destined for more. Nora has no idea how right she is.

A group of rogue Chinese vampires target Nora who, according to a centuries old myth, is the embodiment of the collective energies of all the souls that have ever or will ever exist. For the vampire who can possess her life force that is infinite power. For Nora? Death. For the world? Oblivion.

Nora is forced to trust another sect of these vampires in order to stop the evil that will destroy all life as we know it.
