Wedding Night by Sophie Kinsella
Rating: Really Good ****
Lottie is sure that her boyfriend Richard is going to propose to her at dinner, and when he doesn't she breaks up with him terribly embarrassed and hurt. She reunites with Ben, a boyfriend from 15 years ago, and agrees to marry him not knowing how he has changed over the years.  Lottie is determined to make her honeymoon a night to remember.   She and Ben decide to refrain from sex until their wedding night. The two elope and anxiously head for Echinos, the island where they first met and had a summer love affair. Enter Lottie's divorced sister Fliss. Fliss is a travel magazine editor, and pulls strings at the 5 star resort to prevent Lottie from consummating her marriage to Ben in hopes they can get an annulment.  Funny, enriching story that examines the relationship between sisters, lovers and friends.
