I could only say this, I'm addicted to this audio set. The consistency of the voices is amazingly acurate. I have to say she does a great job..
I've always found that the audio versions of the J.D. Robb books are more enjoyable to listen to over read due to Ericksen's narration.
I listened from start to finish !!!! Loved this book my new favorite until the next one comes out!
