One star, why one star? Because, if you have ever read chick lit with generational characters, you have read this book before. There is a young girl/woman with an abusive boyfriend, a 30 something who really hasn't formed an attachment to a man in years, and an 80 something grandma, who you will love. And just like every other book like this, exactly what you think will happen happens. No, aliens don't land, natural disasters don't occur, and the only exception is a lottery/contest, but that is what brings these three women together.
If you want to meet three characters you have met before (and, yes, for a beach read this might be what you want), then pick this book up. If you want great insight into these characters, well, they are so cookie-cutter, there isn't much more than any other book. But a warning, as you read this book and say to yourself "I wonder if _____ will happen as it did in the last book", for the good and bad, it does.
