"The Masked Man possesses a powerful magic potion that turns every book it touches into a portal, and he is recruiting an army of literature's greatest villains! So begins a race through the magical Land of Oz, the fantastical world of Neverland, the madness of Wonderland, and beyond. Can twins Alex and Conner catch up to the Masked Man?"--
Some of the ideas in the book are interesting, so it is a shame that they (along with the characters) are very badly developed and that the writing never improves in the course of all the books.
