I have read all four main books in the series.
I am not particularly enamoured with Lawrence as a character, nor do I care much for Loveday Graham. In fact I think Lawrence is an idiot. Hopefully he can extricate himself from his current status. The ending was a surprise and it will be interesting to see where the next book takes us, as I am curious to see what Violet is up to. Without giving too much away, I suspect some grovelling is in order. The storylines are interesting and obviously in tune with the period in which these stories are set.
It took me a while to get into the series due to my antipathy towards Lawrence and Loveday.
