For an erotic historical romance not bad at all. I'm always wary of historical romances published by those erotic orientated e-publishers...nothing's wrong with erotica per se, but combined with historical setting it often results in such glaring mistakes (obviously the author and publisher both think that a number of hot scenes can sufficiently disctract the reader's mind so no research is necessary) that I simply cannot suspend my disbelief. That doesn't mean that mainstream publishers don't publish historically hilarious books, but e-publishers are even less discerning.
However,this one was a good surprise. Okay, so I don't believe in an impoverished gentlewoman turned wall-climbing thief (and with a craftsman father and housebreaker ex-fiancee to boot), and her working as a single female salesgirl in otherwise male-staffed shop, not to say selling male wear...that's quite in the realm of fantasy, given the times. All in all, the heroine doesn't become real in the novel, though I can't say I didn't like her. She's a wise woman always reading her complex man's mind - wish I could! - and that reminded me of Genevieve from Loretta Chase's Lord of Scoundrels (love that book). Still, for all my love of independent female protagonists who aren't idiots at the same time, this one didn't convince me she isn't time-travelling. Or is a male pretending he's female.
It doesn't help that the book doesn't have much to anchor it to some historical period or other - it's set in a kind of imaginary 19th century, Victorian-like, but nothing more tangible.
The main focus is, of course, the hero, who is all you (traditionally minded enough to like historicals) would wish for in a hero. He had a hard upbringing, is somewhat emotionally damaged but didn't turn in a demonstrative rebel and/or cad as many such heroes are prone to do. Quite likeble but not dull, and convincing, too.
The instant attraction part and the subsequent sex with a stranger was also prettily done in this book. Usually it's the thing I most cringe at in paranormal and contemporary romances - in historicals I just drop the book and don't read further. Here it was under the influence of drugs and had a convincing dreamlike quality about it, when people indeed act upon their desires while the rational mind isn't turned off completely (which I don't believe it can, given that you have one), but looks at the body from a distance. Sweet sex scenes and not kinky at all.
A good and relaxing read.
