Romance fiction - even Regency romance - is not normally my choice in reading material, nor any of my preference, but my library's summary of this story intrigued me, and as I had one space left for ebook loans I decided to try it. I'm glad I did.
With most of the romance fiction I've ever tried to read (I specify fiction as I quite like romantic fanfiction, already knowing who the characters are and many of their possible motivations), I've found the major, and especially minor, characters far too thinly drawn for my liking, or else overdone in a way that means I lose much of my empathy or sympathy with them. That's not the case here. Leading lady Mira Markham is a sparky young woman of 18, who has been raised largely through ignorance by her parents, who spent all their time concentrating on her more obviously beautiful elder sister Drusilla - this to the detriment of the spoiled sister far more than to that of Mira, who has developed character and strength that Drusilla has not, and it shows. Mira's actions are initially so childish and scandalous that she is threatened with being sent home, but once she begins to mature in truth, she controls herself better, but as an innocent still lets herself in for things she has no idea to expect. All this makes her character far more relatable than her sophisticate sister, though Drusilla is not left to be two-dimensional throughout.
The male characters are about as balanced as the females, and even down to the minor characters we are given at least some idea of their motivations, which I feel is much better than the way Harlequin/Mills & Boon seem to come across to me most of the time, with characters who do things to advance the plot just for the sake of doing them. Here, the characters' actions follow well from their given or implied motivations, which makes the story much more coherent.
Of course there are recurring tropes from the genre - as soon as a certain character appeared I knew how Mira would end up, but getting to that end is fun and less predictable than the traditional fashion, both for the reader and several characters. I think I'm going to seek out more of this series, though I couldn't get interested in Agatha Raisin.
