In this final installment of Lauren Willig's Secret History of the Pink Carnation series, Willig returns once again to the story of the Pink Carnation herself, Jane Woolston. It's 1807, and Jane finds herself in Lisbon, Portugal and in need of the help of Jack Reid, known in the spy underworld as the Moonflower. He's a double-agent with duplicitous alliances, someone Jane is extremely hesitant to enlist the help of, despite his knowledge of the local tongue and his apparent loyalty to the British crown. As the story progresses, Jane and Jack are forced to recognize each other as the individuals behind the flowery disguises and find themselves falling in love with each other.
In typical Willig fashion, this book delivers and enjoyable mix of history, romance, and light-hearted action revolving these 19th century spies. I appreciate the ease with which Willig tells her stories as well as her ability link her books to previous works in the series while still focusing on the main characters of the current book.
