Shifting Darkness — Yvonne Nicolas

An unseen war is brewing in the shadowy underworld of London. Dr. Faith Miller, a local pathologist, is exposed to the horrific reality when she stumbles upon her brother consuming the flesh of his lover. Tajaé Zhang, the second in command of the UK based black panther pack of the Chalvaiz clan, and his fellow shifters have been systematically exterminating the walking corpses -- zombies, in an attempt to control the rapidly spreading demon virus. Secretly, he has observed Faith from afar for months. His attraction for her has grown into an untamable love. After she's bitten and infected with the virus, Tajaé defies the laws of the shifter packs and puts his life on the line to save hers.
