First Brood: Lost Brother

The Lilim have always had their secrets, feasting on humanity in the shadows for thousands of years. Some secrets are buried so deep, even other Lilim are unaware of the danger lurking in their midst. Now not only Auris, but the entire world may be consumed when one of these secrets is let loose.

This is the third book in the First Brood series and it is highly recommended to read the Dreamhunter and Greenhouse first.
