Sink or swim. Once again Abby and her brother Jonah go through the magic mirror in their basement, and this time they find themselves interfering in the Little Mermaid story--and needing to set things right and make sure everyone has a happy ending. If the shoe fits. On their second adventure through the magic mirror Abby and Jonah find themselves in the Cinderella fairy tale--and that is when things start to go really wrong. Fairest of all. After moving to a new house, ten-year-old Abby and her younger brother Jonah discover an antique mirror that transports them into the Snow White fairy tale.
