Cassandra Burke thought she was just a scholar, a scientist, an outsider. Her work on Lumière, a serum that allows vampires to walk in sunlight, was meant to change history. Instead, it made her a target.
In the ancient vampire city of Nivara, Cassandra finds herself at the center of a war between those who crave the light and those who worship the dark. Cultists rise, banished Ancients stir beneath Shadowkeep, and every path leads closer to chaos.
Then there is Dominic. A vampire both protector and temptation, who insists Cassandra is the Bloodlight, the one destined to bring peace or unleash hell.
The closer she draws to him, the harder it is to resist. And the harder it is to survive.
