One of the hundred books a year I read:

In the days after the JFK assassination, a member of the New Orleans mob is running for his life when he does the unexpected (even to himself)—he stops to help a woman with her broken down car. She has her own reasons for being on the road and he decides having her, her daughters, and their dog in a car with him could be a perfect disguise. Together, they set off across the country to Las Vegas and each do the unthinkable—they fall in love. They aren’t just running from their old lives, they are heading to a new life, but can they find it?
