For many years while she was a student and then a tax lawyer, Sharon Kay Penman (1945-2021) worked on a novel about the life of Richard III and The War of the Roses. After the original manuscript was stolen from her car, Penman rewrote the entire novel that would become The Sunne in Splendour.

Penman is the author of ten critically acclaimed and New York Times best selling historical novels and four medieval mysteries featuring Justin de Quincy. The first book in the series, The Queen's Man, was a finalist for an Edgar Award for Best First Mystery from the Mystery Writers of America.
