Having read practically all KLV full length medieval novels, it's a bit difficult to get into her Regency world. You recognise her terse style, the characters move in a world which is familiar, but the book was far too short and so the characters all too predictable. The story itself is equally bland. However, it was very interesting to see names from her medieval world reappearing, de Wolfe, de Winter, de Lohr even the infamous pub the Pox which features so often in the Executioner Knights survives to the 19th century.
I want to believe that it is Kathryn's way of winking at her faithful readers and not that she has run out of ideas for pub names!
So, I would suggest that if she wants to continue with adventures in the Regency period, she should imagine more complex storylines which would keep us to the edge of our seats, just as she has done in her most recent series The Blackchurch Guild.
