High Cotton by Debbie Mayne
Here is the book description and author bio from the publisher.
Some families are filled with so much love they can’t help but drive each other crazy
Shay Henke has mixed feelings about going to her family’s next reunion. On the one hand, she’ll get to see everyone in her mama's family—folks she loves unconditionally. On the other hand, she knows there’ll be more drama than you can shake a stick at.
The days leading up to the event bring one surprise after another. First Shay must deal with her sister-in-law’s deep, dark secret. Then she has to contend with the childish ways of her business-mogul twin cousins. And when her high school crush wants to be her date to the reunion . . . well, it may have been a dream come true for Shay’s teen self, but the woman she’s become doesn’t know what to make of this.
Shay’s contentment is challenged, and she’s determined to shake things up a bit. But will she find the excitement she’s looking for, or will Shay realize she prefers her quiet and predictable life? One thing is certain: Life in the Bucklin family is never boring.
Debby grew up in a military family, which meant moving every few years throughout her childhood. Debby was born in Alaska, and she has lived in Mississippi, Tennessee, Oregon, Florida, South Carolina, Hawaii, and Japan. Her parents were both from the Deep South, so she enjoys featuring characters with southern drawls, plenty of down-home cooking, and folks with quirky mannerisms.
She and her husband currently live in the Charleston, South Carolina, area.
