How to Read Diana Cosby's Books
Diana Cosby has crafted three distinct historical romance series set in the medieval era, alongside a notable paranormal romance anthology contribution. Because each series features its own set of characters, storylines, and themes, the simplest and most satisfying way to read her books is in publication order within each individual series.
There is no overarching chronological order connecting the series together, so you can pick up any of the three major collections first. However, the internal storylines of each series build on character relationships and political intrigue, making order essential for the best experience.

This is Cosby's flagship series that put her on the historical romance map. Starting in 2007 with her debut novel, the series follows the fiercely loyal MacGruder brothers as they navigate the turbulent landscape of medieval Scotland, fighting for their homeland and finding unexpected love along the way.
