Katherine is considered Seton's most well-known work as well as the best-known depiction of Katherine herself. It is commonly regarded as a prime example of historical fiction and romance, with Vanora Bennett of
The Independent noting in 2010 that it "set the benchmark in
high-medieval romance, and few have matched her since". It has been continuously in print since its publication date. In 2006, Margaret Moser of the
Austin Chronicle described the novel as "a glorious example of romance in its most classic literary sense: exhilarating, exuberant, and rich with the jeweled tones of England in the 1300s". given that Seton was not a historian or
paleographer and was working in the 1950s, when sources were less widely available. It diverges comparatively little from known history, though since archival documentation of Katherine's life is limited, it does contain some necessary conjecture. Though subsequent non-fiction accounts of Katherine, including those by historians
Alison Weir and
Jeanette Lucraft, make clear that Seton's various speculations were partly and sometimes significantly incorrect, the novel does provide the reader with a reasonably accurate view of
medieval England, life at court, and the lives of women in the 14th century, along with intelligent and sensitive glimpses of Chaucer, Katherine's brother-in-law. In addition,
Katherine is one of the few fictional texts that include writings by the Blessed
Julian of Norwich, a character in the novel, who is considered one of England's greatest mystics and whose
Revelations of Divine Love was the first book written in English by a woman.
Katherine is also considered one of the greatest examples of a historical-fiction love story ever written. In a poll conducted in the 1990s by ''
Ladies' Home Journal'', the novel ranked among the top-ten all-time best love stories. Weir was inspired by
Katherine to become an author of historical fiction, and the novel would also later inspire her non-fiction study,
Katherine Swynford: The Story of John of Gaunt and his Scandalous Duchess (2008) (U.S. title,
Mistress of the Monarchy, The Life of Katherine Swynford, Duchess of Lancaster). It examines Seton's novel in
historiographic terms and, while praising its general historical accuracy, categorizes it as primarily a feminist romance. == Other editions ==
