I love this book for a number of reasons, not least because it is well researched and intelligently written. The best bit though for me was getting to hear about the Wars of the Roses from the "other" side. Granted, it's not as much fun as being on the Yorkest side, but it was a refreshing change and sensitively done. The clincher for me was that by the end I was so emotionally involved with the characters that I cried (something that rarely happens) and would've given anything for the outcome to have been different.
This author just keeps getting better and better, and I can't recommend this book highly enough!
