From a beautiful old country home set among live oaks and roses facing the temperamental Gulf waters of the Mississippi Coast to the bewitching city of New Orleans and the hypnotic swamps and bayous to its south, three middle-aged sisters find themselves entangled in a series of mysteries they are determined to solve.

In the summer of 2010, the Meriwether sisters, Vy, Rose, and Indigo, return to the Mississippi Gulf Coast to live in their family home after spending years apart pursuing their own endeavors. Three years later, as they start to relax after renovating their home and gardens, Indigo finds a mysterious trunk in the brimful attic she is cleaning out to refurbish as an apartment for herself. The sisters are curious about the paintings found inside that were mailed to their great-grandparents in the 1940s, but they cannot find any explanation as to where they came from or who the artist was.

As they mull over this discovery, the sale of a nearby home sends them peeking out windows and knocking on doors trying to catch a glimpse of their new reclusive neighbor. Only random lights at night and an occasional twitched curtain suggest that anyone lives there.

Then a spontaneous trip to New Orleans sends them on a mission to find a young girl they believe might be in danger. Following leads that take them into the swamps south of New Orleans, the talents of all three sisters are needed to guide them: Vy's artist's eye, Rose's sleuthing, and Indigo's intriguing instincts.

Written by three sisters, each creating her own character, the fictitious Vy, Rose, and Indigo have distinct personalities and led independent and far-flung lives before coming together under one roof in the house their great-grandparents built overlooking the ever-changing waters of the Gulf of Mexico. Independent, caring, smart, carefree, fearless, funny, and hospitable, these women are a testament to Southern women and all people living life with humor and zest.
