I normally do not like secret keeping as a plot device, but I didn't mind it too much in this book. Mostly because so much of the plot was absurd to begin with that the secret didn't seem so bad, at the beginning. Basically, according to her father's will Fiona has to marry otherwise her younger sisters do not get their dowry's. To that end, he has arranged a marriage for her with a man she has never met. She does not want to marry a stranger, so with the help of her cousin Oliver, she decides to ask Jonathon to marry her. Jonathon thinks this is a prank being played on him by Oliver and the rest of his friends, so he says yes. Then, when he discovers it's real he says no. But, because he feels guilty, he agrees to help her by writing a book with her, a naughty book. They will publish it anonymously, but here is where the secret comes in: he's only going to publish a handful and then in secret will provide her the money, saying it came from the sale of the books. Well, during the writing process they fall in love, which is exactly what Fiona wanted. He messes it up multiple times. But, with the help of her new friend Judith, also a friend of Jonathon's, she gets him to realize he loves her too. But, Judith accidentally lets the secret slip, Fiona finds out the truth and they break up. Her betrothed shows up and he's wonderful; tall, dark, handsome, and charming. He didn't want to get married, but agreed once he heard the stipulations of the will and they agreed to be married for a year and then dissolve it. Well, cousin Oliver introduces Daniel (betrothed) to Jonathon and friends and the develop a plan so that Jonathon can make a grand gesture and marry her, and Daniel will still get the money. Turns out he's really a stand up guy and Daniel becomes friends with everyone. Jonathon and Fiona get married. Oliver and the rest of the guys make a small "bet" about who will be the last one standing; and Daniel is included. I am looking forward to Oliver and Daniel's stories, as well as the stories about Fiona's sisters. I expect that there are still 3 sisters and not counting Oliver, 3 friends so it's possible that they all marry a sister.
