The Carmichaels and Grahams have gathered on Nantucket for a wedding. Plans are being made according to the wishes of the bride's late mother, who left behind the notebook: specific instructions for every detail of her youngest daughter's future nuptials. Everything should be falling into place for the beautiful event but in reality, things are far from perfect. While the couple-to-be are quite happy, their loved ones find their own lives crumbling. In the days leading up to the wedding, love will be questioned, scandals will arise, and hearts will be broken and healed. Elin Hilderbrand takes readers on a touching journey in "Beautiful Day" into the heart of marriage, what it means to be faithful, and how we choose to honor our commitments.
