Little Sister used the Three Muskehounds to help me revise for my History A-level. I did British and European 1485-1660 (although for British we stopped in 1649) so it is probably designed for readers who are me except I read my mother's copy of Here I Stand at the time and I think that's still enough Luther biography for the time being.

I don't think Hilary Mantel is the right person to judge whether anything about the sixteenth century is accessible. She will be differently calibrated.
