London 1814...

Drake, Duke of Manchester is searching the Marriage Mart for a perfect bride. He wants a woman who is poised, sophisticated, and worthy of the title Duchess. But most of all, he wants a woman who does not want the useless emotion of love. 

Socially awkward Miss Penelope Clayton isn't meant for marriage. A serious botanist, she has no desire to wed, so being forced by her guardian to participate in the Season to find a husband is torture. She'll never fit in with the ton, especially if they discover she's been pretending to be a man within the scientific community. 

As Drake's family makes over Penelope, turning her from naive bluestocking to enchanting debutante, he is put upon to introduce her to society and eligible bachelors. Despite dance lessons and new gowns, Penelope is the opposite of poised and sophisticated as she stumbles from one mishap to the next. Why then, does he find it so hard to resist her?
