Resa Folchart is Mo's wife and has been separated from him for 9 years. When Mo was reading Inkheart he accidentally read Capricorn, Basta and Dustfinger out of the book and her into it. This made him never read aloud again, fearing for his daughter's safety. Resa was read back out again by Darius, Capricorn's "slave" silvertongue. Due to the bad reading of Darius, Resa left her voice in the Inkworld. She was mute when she lived as a slave to Capricorn's mother, Mortola, and was mute when she lived with Meggie and Mo, and spoke by tracing words in the air with her finger, or by writing, until she was read back into the Inkworld, where she and her voice united once again.
