I have finished "The Devil's Queen" by Jeanne Kalogridis and boy was it a fast read. Over four hundred pages of history, court intrigue, astrology, I couldn't put it down. For me not to know anything about Catherine De Medici I think I have a pretty good understanding of her after reading the book. What a powerful woman. What a determined woman. Wow! I highly recommend this book if you like historical fiction. If you haven't tried historical fiction....well your missing out.
