Hi Deborah. I read this book for the first time relatively recently and loved it. I was also thinking of getting Alison Weir's book -its on my Wish List. I enjoy books which mix accurate history with some fiction. The Fates would have been perfect for me had it been what is was cracked up to be!
BTW I have re-submitted my Ideal Wife review for now so the comments have disappeared. This afternoon was really creepy for a while - I really hope they are all banned.
Don't want to come the TG fan with you but have you ever read or heard of Dorothy Dunnett - the Lymond Chronicles and the Niccolo books? I have reviewed them - can't recommend them highly enough if you are into that sort of thing.
