but I can see them.

Now Amelia has the chance to solve the puzzle to the questions that have plagued her for years.

As she embraces her true identity, Amelia, along with her monster friends, are zapped into ancient worlds where butterflies talk, gnomes become spies, and allies turn into enemies as she seeks to discover the truth.
