Invisible Friend [EPUB ebook] 

Once again Bree finds the courage to win in a story that builds on the first two books of the Viking Quest series. In this novel, Bree arrives in Norway and is sent to work as a slave for the family of Mikkel, her Viking captor. She struggles to adjust, feeling worthless and disrespected, and wondering why God wants her in Norway. Her prayers are answered when she is given the opportunity to teach Mikkel’s grandparents to read using an illuminated Bible stolen from an Irish monastery.
