Accessible and easy to read biography of Katherine of Aragon and Juana of Castile. Like many of Alison Weir's bios this offering from Fox reads more like a novel than a bio and is pitched often in quite simplistic terms. There were several stylistic quirks that drove me nuts but on the whole it was a solid read even if Fox sometimes falls into the trap of stating as facts things that we cannot possibly know for sure. There's not a whole lot new here but it is presented from a slightly different angle than most other stuff about these two Queens which was nice.
Be warned though, the pages are not equally divided between the sisters with Katherine hogging the most space. If you are looking for a good book on Juana, this is not it.
