I'm not sure specifically about a 'Linda Byler' in 'Fantastic Fiction'. There could be many characters and stories within that realm. It might be a relatively unknown or a very specific reference that I'm not familiar with.
Smut fiction is a type of fictional writing that contains sexually explicit content. It often focuses on sexual encounters, relationships, and desires. However, it is considered a form of adult - oriented literature and may not be suitable for all audiences.
Well, a smut novel refers to a book where the focus is heavily on sexual themes and often has very detailed and graphic descriptions of sexual acts. It's not for everyone and is usually considered more adult-oriented.
