There is a lot of literature based on the Alice in Wonderland books. Shortly after the first book was published, a writer named Anna M. Richards wrote a book called A New Alice in the Old Wonderland. It was about a girl who had read Alice in Wonderland and visited the place herself. From what I understand, she meets all of the same characters, though her experiences differ.
There are still writers creating retellings of the books. More recently there have been a lot of graphic novels and comic books telling the story of Alice in Wonderland. Many people think that these types of books are a great addition to the series. Of course, some of these works beg the question of what, exactly, can be considered original literature. I think this is a problem with a lot of literature written in pastiche. But there are some really great works written in this style, and I would be wary to write it off completely.
