I think this might be my fave Heyer novel so far, it's enchanting to read, and I couldn't put it down for a minute!
It's about beautiful but relitively poor Arabella Tallant who gets to go to London for the season to come out, under the guardianship of her godmother, Lady Bridlington. On the way, she is obliged to take shelter under the house of a gentleman called Mr Beaumaris who is having dinner with his friend, Lord Fleetwood. Mr Beaumaris thinks she is just another girl trying to get hold of his wealth by some elaborate scheme, and Arabella, so annoyed with him, and thinking that she'll never see him again, pretends to be an heiress of enornmous wealth.
When she arrives in London, she finds that her reputatuion has got there faster thanks to Lord Fleetwood's big mouth and soon, every dandy, buck, fop and fourtune hunter are after her. And she meets Mr Beaumaris again, who knows the truth, but lives in hope of Arabella falling in love with him and telling him the truth, unknowing of the fact that he is already half in love with her himself...I know, SO romantic!
The ending ties up well with Robert Beaumaris taking care of the mess that Arabella has got herself into and that of her brother, young Bertram Tallant. You can't help but fall for this hero yourself and the ending is so satisfying, and Beaumaris is all knowing and arranges their marraige...sigh...I can't praise this book enough, just buy it, read it and you'll see what I mean. Just Fantastic!!
