On a long trip, I listened to this book on CD in the car. The story kept me engaged and helped pass the time and miles. A father with a wife and daughter marries another woman when she gets pregnant, and they produce another daughter. When the girls are teens, they meet, though one doesn't know it at first. The second daughter and wife know about the first but the first family knows nothing about the second. I enjoyed the characters in the book. Realistic situations and dialog.
