I just today finished reading Leanda de Lisle's
The Sisters Who Would Be Queen, a book about Ladies Jane, Katherine, and Mary Grey. It covers many of the same events as Allison Weir's
The Children of Henry VIII, which I
also read not too long ago. One difference is that Weir's book was focused on the Tudors proper. It was primarily about Edward, Mary, and Elizabeth. Lady Jane Grey was its fourth subject, as she undeniably had an effect on the aforementioned monarchs. Weir didn't really say anything of substance about Katherine or Mary, while de Lisle does.
Jane can still fairly be called the first among equals in this book's telling, exactly because she was the shortest lived of the sisters, or rather because of the reasons she died so young. She's a troubling figure in some ways. She was serious, humble given her social position, an avid reader. She was also, by any objective standard, a religious zealot. Her vision of Protestantism was markedly similar to what the Cromwells would promote the better part of a century later. Elizabeth I was no sweetheart, but she did bring some kind of religious equilibrium to England during her reign. It's hard to imagine Jane doing the same.
Even given more attention than I've seen them get before, it's harder to get a read on Katherine and Mary. Lady Katherine Grey could have potentially become queen if Elizabeth's bout of smallpox in 1562 had gone worse for her. And at that point it was pretty much Katherine's only hope for freedom. What kind of queen would she have been? Unlike her older sister she hadn't made any big political or theological statements. She loved her husband Edward (like bunnies, I tell you), she loved her two baby sons, and she loved dogs and monkeys. As queen she might have deferred to Edward, but even he was more of an upper class striver than an aspiring ruler.
Then there's Mary. Like Katherine, she had married without Elizabeth's knowledge or permission, and was punished for it. An odd match, as she was a borderline dwarf and husband Thomas Keyes was a borderline giant, but they seem to have clicked on some level. While she was at the top of the succession chart after Katherine's death, she plainly had no great interest in usurping the throne. Elizabeth eventually realized this and freed her. Sadly it wasn't too much later that she was struck down by the plague.
The book is a triumph for de Lisle. She makes her mostly lesser-known historical figures come to life.
