Guardian of the night - Linda Thomas-Sundstrom

Their passion could be their destruction The Guardian: an immortal with incredible strength, created centuries ago to protect the purity of the vampire blood line and fight those who would abuse its power. As one of the seven Blood Knights, Mason LanVal spent lifetimes honouring his vows.

Then he found Faith. Faith James would do anything to save her missing sister. Even risk her life. She sought Mason for help. Instead she found more questions and the key to her own Lycanism. And, with just one kiss, the blood gift Mason gives Faith sets in motion an all-consuming, forbidden desire.
