“The main problem with this biography is what Weir acknowledges at the beginning of the book: there's no personal *anything* remaining of Katherine Swynford - no correspondence, no personal articles or possessions, no diary, no will, and no direct biographical examination of her by anyone who knew her directly. This means that everything Weir says about her is basically conjecture, even if it is meticulously researched conjecture.
There was a lot of information here that, frankly, I didn't care if I knew, and nothing about Katherine's (or John of Gaunt's) personal feelings. However, reading it did fill in some of the gaps of English politics in the late 14th and early 15th centuries, so it was in that way, worthwhile. ”
