Knights of the Castle continues the Castle universe created by Naleighna Kai, with eight books published in 2020. Like its predecessor Kings of the Castle, each entry is written by a different author and follows a new character in a standalone romance. Titles like Knight of Bronzeville, Knight of South Holland, and Lady of Jeffrey Manor indicate the neighborhood-based naming convention carried over from the first series.
The series expands the world built in Kings of the Castle while maintaining the same multi-author collaborative format. Each book can be read independently, but the shared universe gives returning readers additional context and connections between stories.
