I’m currently reading Daughters of the Winter Queen by Nancy Goldstone. It’s an interesting book (about 50% of the way through) about James I’s daughter Elizabeth and four of her daughters. While it’s supposedly about the daughters, there’s a lot of history of the English Civil War and the 30 Years War in this book as well.
I’m liking it so far. Goldstone is a great author and I’ve always enjoyed her books.
