The Unseen is book two in The Order of the Bell series. I advise that you read book one, The Carver, first (it’s on Litpick's website too!) because book two is a continuation of the adventure.

In The Unseen, Crescenzo, Rosana, and Zach are now in Wonderland looking for a way to stop the King of Hearts, who teamed up with the evil Queen Avora, who has trapped their parents. The main characters, Crescenzo, Rosana, and Zach, are the sons and daughter of Pinocchio, Alice in Wonderland, and Peter Pan, respectively.

The Unseen is a book continuing Crescenzo's (Enzo's) adventures. Following the last book, Enzo, Rosana, and Zach are trapped in Wonderland with no way of getting out. After freeing their friends from the gems, Enzo and Rosana are still as far away from their families as before. The evil Queen Avoria is now free, and the children are seemingly the last hope against her. Queen Avoria has grown extremely powerful, and it seems like she's unstoppable.

The Unseen is another fantasy tale that combines fairytale characters and settings in one story with a trio of young heroes. It is the second book of a trilogy, and due to the large number of characters, a reader would need to read the first book to avoid confusion. Rosana, Alice's (previously from Wonderland) daughter, is lost in Wonderland with Peter Pan’s son (Zack) and Pinocchio’s son (Crescenzo).
