Nothing glaringly bad about this story, but nothing to trap your interest and keep it either.
Basically, the plot centres on a young deb's dreams of a titled husband, driven by romantic illusions rather than cold ambition.
I couldn't finish reading the book, it was all too bland with 'dot to dot' plotting.
Also, I have read several other Carola Dunn's Regency romances, some are much better than this, but I really feel those who compare her with Heyer, as if an equal, are perhaps too readily satisfied.
Although I admit I sometimes find a few of Ms Heyer's novels unevenly paced, they at least have occasional moments of briskness when something interesting happens.
Also, Ms Dunn does a poor service to the Irish here, her Irish aristocrat is a feeble and inaccurate caricature, as with many other of her minor characters (servants in particular).
In fact, I would say the thing Ms Dunn's books have most in common with Ms Heyer's works is her cut and paste lifting from Ms Heyers plots.
