This is my favorite era for historical fiction, mostly because there was so much going on in the English court that there's an excellent backdrop of real drama. Weir certainly doesn't disappoint here, and I thought she did a fabulous job of this, including a brief section of notes at the end that describes what's based in history and where she took liberties (she's a scholar of the period). I did have trouble keeping the two Kates straight some times, and this was compounded by a typical ebook problem of not being able to actually read the family trees in the front of the book. It was very interesting to compare and contrast these two young women, though, as they make decisions that will have huge impacts on their lives and the lives of those around them. Kate Plantagenet in particular was a frustrating character for that reason, but this is part of what makes it all so believable. If you enjoy reading about this period I would encourage you to pick this up when it comes out (I read it as a galley).
