Well defined characters to the point of distraction. I caution you about driving and listening to this book you may start laughing and not be able to see where you’re going, as I did. this series is a must if you need a lift. I will warn you the language can be offending, but I think that’s what makes it funny. The story is well laid out and very enjoyable. I love Robyn Peterman. She always makes me happy.
