It was a brand new series, actually, called 'England's Forgotten Queens' and edited by Alison Weir.

Weir? That may explain a lot... I know a lot of people in English mediæval history regard her as not much better than a historical novelist... Tends towards the romanticised and sensationalised...

And there's a reason a lot of these characters are "forgotten". They're consorts, and very few of them (Woodville being one of them) made an impact in their own right.

Have you raised these books on the plantagenesta forum? Should provoke a fair bit of discussion there!
