European Royalty discussion

Anyone know of any books about her, either fiction or non-fiction? I could only find Jean Plaidy's "The Battle of the Queens" and a bio written about her in the 70s which seems to be out of print now (can only find it used). I'm surprised because she's seems like an interesting subject.

I'm more than willing to read Jean Plaidy's but I was hoping it's not the only one.

"Blanche of Castile" by Régine Pernoud (whom I personally love as an author)
"Capetian Women" by Kathleen Nolan (has an entry)

Thanks, the first one is the one I can only find used, the second one I'd really like to read but it's very expensive! I can only find it on the US amazon so I'd have to import it to the UK, making it even more expensive. Between shipping and VAT, it'd be about $90/£60. I think I'll stick with Plaidy's but thanks!

try to get it from Bookmooch...
