As a kid, I constantly felt lonely and apart from my environment. As I grew, so did that feeling. Reading was my only vice.
In these books, the characters could be unique or “weird” and still have outstanding adventures. For someone who dealt with people telling them who they could/couldn’t be, and constantly being asked why they can’t be “normal” literature was fun for me. Because if everything went on “normally” in books, nothing would happen.
Others can get involved in books as well, if they feel represented in what they read. So much old literature has been lost in translation that people can’t relate at all. If modernity is applied, that barrier can be fixed.
