My Darling Coquette — Valerie King

THEY WERE BOTH AS MAD AS BLAZES...
Never in her life has Coquette Florencia Millbrook been so furious, and with just cause. For her guardian, the recently departed Sixth Earl of Harlington, has made sure her entire fortune will be out of her reach until she weds. What's worse, his son--a man with whom she has spent her entire life at loggerheads--will not receive a tuppence of his own inheritance until she marries. It's enough to make an heiress swear...and then scheme...to turn herself into the sort of intoxicating beauty who will have a legion of suitors vying for her hand...

...UNTIL LOVE KINDLED A DIFFERENT SORT OF FLAME
Ever since they were children, Coquette Millbrook has been a thorn in Harley's side. And now, thanks to the outrageous terms of his father's will, the young Lord of Harlington is once again at her mercy. It could be an eternity before he receives his due, for what man in his right mind would have such an exasperating female? Yet the darkly handsome Harley is in for a shock--because beneath those atrocious manners and ragamuffin garb is a veritable temptress. And only after she finally is betrothed does Harley begin to realize his true feelings for his darling Coquette...
