Spelled in Shells (Every Grain of Sand #1)
Elisabeth Mayer

She had worked diligently to move on, away from Jesse and was enjoying a successful career and a fulfilling love life with her new boyfriend, Billy Thompkins that seemed to be headed toward the altar. However, with Jesse back in her life, Nikki finds herself battling familiar old feelings while working to forge relationship between Jesse and their three-year-old daughter, Kathy.
As the summer approaches, temptation continues to grow; the heat between Nikki and Jesse becomes unbearable and all too soon she is swept away...like seashells on the sand.
