Anwil and Ariadne Pendragon are twins, best friends, but nothing alike. While Anwil pores over books in the library, Ariadne is training to be a Knight of the Round Table. Yet they are both haunted by the same shadow: their late father, the legendary King Arthur.

It's been nearly twenty years since Arthur died in the Battle of Camlann, and peace has since prospered under the regency reign of Queen Guinevere. Camelot has grown into a bustling trading hub and Briton is flourishing. But not everyone is happy with Camelot's growing power.

When abbeys start burning and relics go missing, a war like no other looms over Camelot, and Anwil and Ariadne are forced to face the harsh realities and lies their mother has tried so hard to shield them from.
