This book very much reminded me of a Regency romance with the London setting, the balls, fancy gowns, uses of chaperons etc. I like picking up a Regency every once in awhile to remind me that there's more out there than murder mysteries and fantasy.
Dent does a good job of keeping her characters consistent. The only thing I didn't like about The American Heiress was that I wasn't sure if I was rooting for the protagonist to fall in love with Miles or Lord Stratford. It took me a long time to figure out which one I was supposed to be rooting for.
I can't say I was very shocked or surprised by how this novel ended, but Regency romance are usually a little more predictable than murder mysteries with the happily ever after type endings and the conventions of the sub-genre in general.
I give this one 4 stars **** and would read another Roxanne Dent title again. I enjoyed the novel.
