Wrenn Bailey has lived all her life on Cape Cod with her mother Lindy, older sister Shannon, and younger sister Piper. Growing up, life was dictated by the seasons with sleepy gray winters where only the locals stayed on, followed by the sharp influx and colorful bustle of summer tourists who swept up the elbow of the Cape and infiltrated their small paradise.

But it wasn't just the tourists who interrupted Wrenn's formative years; her father--brilliant but troubled photographer Caleb--has long made a habit of drifting in and out of his girls' lives. Until the one summer he left the Cape and did not return again.

Now, almost twenty years later, Caleb has come back one last time, suffering from pancreatic cancer and seeking absolution. Wrenn and her sisters each respond differently to their father's return, determined to find closure. But that means returning to the past and revisiting old wounds--wounds that cause the tightknit Bailey women to confront their own wishes and wants, and admit to their own wrong-doings over the years. In a place that brings both great comfort and great pain, the Bailey sisters experience a summer on the Cape that promises not only hard endings, but perhaps, hopeful new beginnings.
