Once in college I had to read one of those awful books fetishizing Jane Grey, the very works that de Lisle rails against. Girl, let's talk about how weird those books are. I've kind of hated Jane Grey from that moment on. In class, my peers and I often made fun of how the author must have had some crush on Jane.
Luckily, in this book Jane is a real, live, feisty human, not some weird male historian's wet dream. And, she dies a third of the way through the book, which I enjoyed. Her sisters come alive too, along with the very real dangers and opportunities they faced.
Tl;dr: Jane dies and ruins it for everyone and I enjoyed this book immensely.
