Annie O'Harran is frazzled with all that is going on in her life. Besides being a single mother to her twelve-year-old daughter, Flora, Annie is planning a wedding to her doctor-boyfriend David and trying to finish a novel in time to meet the publisher's deadline. She decides that her best option is to get out of London and head to David's elderly aunt's home on the Cornish coast. So Annie and Flora pack up and head to Cornwall, blissfully unaware of the mishaps that will follow them there.

The first night, they are awakened by strange noises from downstairs. Thinking they are being robbed, they sneak down to find Matt Malone, an American who rented the house from doddering Aunt Gertrude many months ago. Matt and Annie come to a tentative agreement: they will share the large home until they can work out another arrangement. But a few days turn into a couple of weeks. David doesn't visit as much as he had promised, Annie's sister, renting a home nearby, has difficulties with her own husband, and Matt's son comes for a visit. The relaxing summer Annie had planned goes completely haywire, but she discovers this isn't such a bad thing after all.

The Wedding Day is an amusing British chick lit book. Readers will find themselves immersed in the characters' lives, particularly Annie's, since The Wedding Day is told in her first-person viewpoint. Although the main focus of the book is relationship development, the secondary focus is definitely family. Annie's extended family, including her ex-husband, sister, mother, and even her fiancé's relatives, all blend together and will have readers thinking about their own family dynamics. Annie is blind to her own weaknesses, especially when it comes to romance, but they are clear to everyone around her. The way she discovers her true desires and matures in her understanding of love is realistic and believable.

The meandering pace of most of the novel fits The Wedding Day perfectly, but the ending feels a bit rushed and tacked on. Other than that, there are elements of The Wedding Day that will appeal to a wide variety of readers. Romance, family relationships, trips to the beach, and friendship all make this a well-rounded, enjoyable read.
