Sink or Swim (Whatever After #3) - Sarah Mlynowski

We weren't planning to mess up the fairy tales. The first two times we did it by accident. But when our magic mirror pulls us into the story of the Little Mermaid, we have no choice but to try and rewrite it. Let's just say the original story does NOT end happily Now we need to: - Convince our mermaid to keep her tail - Plan a royal wedding - Avoid getting eaten by sharks We've got to find a happy ending for the Little Mermaid . . . before she's fish food and we're lost at sea forever
