In the ninth installment of Lauren Willig's best-selling Pink Carnation series, an atrocious poet teams up with an American widow to prevent Napoleon's invasion of England. 

Secret agent Augustus Whittlesby has spent a decade undercover in France, posing as an insufferably bad poet. The French surveillance officers can't bear to read his work closely enough to recognize the information drowned in a sea of verbiage. 

New York-born Emma Morris Delagardie is a thorn in Augustus' side. An old school friend of Napoleon's stepdaughter, she came to France with her uncle, the American envoy; eloped with a Frenchman; and has been rattling around the salons of Paris ever since. Widowed for four years, she entertains herself by drinking too much champagne, holding a weekly salon, and loudly critiquing Augustus' poetry. 

As Napoleon pursues his plans for the invasion of England, Whittlesby hears of a top-secret device to be demonstrated at a house party at Malmaison. The catch? The only way in is with Emma, who has been asked to write a masque for the weekend's entertainment. 

Emma is at a crossroads: Should she return to the States or remain in France? She'll do anything to postpone the decision - even if it means teaming up with that silly poet Whittlesby to write a masque for Bonaparte's house party. But each soon learns that surface appearances are misleading. In this complicated masque within a masque, nothing goes quite as scripted - especially Augustus' feelings for Emma.
