Outstanding!
Format: Audiobook
Outstanding! Engrossing! I couldn't stop listening. It touched my soul on so many levels. I have a deeper level of respect for Ms. Cross, after this book. And having the audiobook spoken in her own voice, made it even more special. I will now have to purchase the hard copy.
