Clark creates an almost cinemagraphic evocation of time and place, with vividly drawn characters, convincingly authentic language, and scads of period detail. Why this hasn't been picked up for a PBS series, à la Cadfael, beats me. I concur with the Guardian's assessment that "Hildegard is an engaging protagonist, sensible, kindly, resourceful and believable."
This page gives some great background on the series and its context.

The Kings and Queens of England by Ian Crofton. Below, a full view of the Yates Thomson manuscript page. These nuns definitely appear to have a great deal of agency in their order's affairs.
