Barefoot by Elin Hilderbrand

This is the story of three women and one young man. They meet in Nantucket. Josh is a college student working for the summer at the airport. One day three women and two children arrive. Since Josh wants to be a writer he is always attentive to what is going on around him in case he can use it one day in a story. Vicky has been diagnosed with lung cancer and has come back to her family cottage to begin her chemo and spend time with her young son and her baby. Brenda, her sister, is basically looking for a place to hide. She had loved the college setting where she had been teaching for two years. But then she became involved with a student (he is actually older than she is - so it's not exactly what you think) and now she is in big trouble. The third woman is Melanie. She had in vitro seven times. Of course she becomes pregnant in the usual way instead. But right before she found out about her pregnancy, she found out her husband was having an affair. Melanie and Vickie are good friends but Brenda and Vickie don't get along. Oh yeah - I forgot about Josh. He ends up spending the summer with them too. An easy read with likable characters.
