Until the Heart Stops (Oylen City, #1)

In the city of Oylen, a vampire contingent called The Covenant has ruled for centuries. Their strictest law? No vampire can drink from a living source. This ban on blood drinking created the Souzterain and the black market blood dens that have now run for centuries to give vampires a taste of what they crave most.

Lilith Searah runs one such business. Her life is constant competition with the other dens, the rules of the Covenant, and the danger her inherited profession poses. But when she catches the eye of a powerful immortal and anonymous gifts arrive, she’ll find there’s something more perilous than running an illegal blood den.

Thrust into the ancient world of vampires, Lilith realizes that the nighttime immortals have been keeping dangerous secrets. The only hope she can keep is that the Covenant can be destroyed and that Lilith and her immortal can finally be together.

That is, if she can make it out alive.
