BAREFOOT is by Elin Hilderbrand, another of her Nantucket Beach books that I always enjoy.
Three women, two of them sisters, head to the beach for the summer. All have baggage. The oldest sister has brought her two young boys and is about to undergo chemo for lung cancer. The younger sister has lost her job as college professor and reputation after sleeping with a student. The friend has found out that, after several in vitro attempts, she's finally pregnant. And that her husband is cheating.
As usual Hilderbrand does a great job of drawing each woman's personality as well as the babysitter hired to help with the boys, a college student who's drawn to each of the women in turn. They all have battles to fight and decisions to make. And we're with them all the way.
Seems to me the entire book is about choices. The choices each woman and the babysitter makes, the choices supporting characters make, the choices all of us might make. Some are good, some are bad, but in the end they must be lived with.
