Sister Queens by Julia Fox ~ Fine read about Katherine and Juana

A fine and extremely well researched book by an author who cared about the subjects that were written about.

Juana of Castile and Katherine of Aragon really did have tragic lives and very few happy times. Did it have anything to do with the "Spanish Madness" experienced first by their grandmother Isabella of Portugal, or was it just the lot of Medieval Princesses?

I have my thoughts,as does the author so I recommend reading it!
