The Summer Home by Hazel Taylor

Miranda has done all she could to live a harmonious live as a mother of two beautiful children, Tianna and Darby. It was supposed to be a peaceful time for her to pursue a new career and possibly begin dating after so many years alone as a single mother. Like any mother of two adult daughters, she weathers the storms of excitement, heartache, and joy.
Miranda, a woman who prides herself on preparing for every possibility could have never predicted a late-night text from her oldest daughter that would change everything.

The text was only the first sign of what will become a summer full of mayhems and surprises. Reluctantly putting a new career on hold and removing all possibility of dating, Miranda enlists the help of her sister Jasmin and soon both of them and the daughters are headed to beautiful Grassy Key, Florida. Deep in the heart of the Florida Keys, this was the place that Miranda and Jasmin called their second home as children.
Determined to straighten the girls out, both women find out how life can quickly turn plans upside down. Memories long since buried are brought back to life and secrets the sisters wish were left hidden in their bedroom closet are aired-out.

Throw sisters, daughters, new romances, and long-kept secrets onto a beautiful island, and what might seem like a relaxing getaway turns into much more. Before the time summer ends, truths are uncovered, friendships are strengthened, love is rekindled, and fate will have its say in more ways than one.
