Fiction- "Perfect" wife and mom walks away from family during beach vacation and begins a completely

I read this book this summer, and I believe it was published this year or last year. 40ish year old wife and mother deserts her family during a beach vacation. She starts walking down the beach and hitches a ride to a new town where she completely reinvents herself. Each new person in her life seems to mirror a relationship she has left behind in her old life. I cannot remember the title or the author - yikes- time to start keeping track on this site. Thanks for any help with this!
