“I received many auditions, and I chose Mary Castillo to narrate as I immediately felt she captured the spirit of the book. It was not an easy task: a lengthy volume with many characters from different places. Her accents, intonations and interpretation of them were brilliant, and she brought the book to life. Mary always read with cognizance of the scene and presence. The tone, pace, rhythm and style were just right. I was so delighted with the reading that I asked her to work with me again on another project! The quality audio recording was excellent, and any requested modifications made to the narration were done swiftly and perfectly.”
