This is a controversial subject: I have known many adult readers who regularly read and enjoy Young Adult or even Juvenile fiction. Since my first “A” at the university was in Kiddie Lit, I have some background in the literary analysis and appreciation of fiction written for the younger set (I also took The Bible as Literature and that too gave me an appreciation of another 17th century work other than by Shakespeare and, contrary to what most believers might expect, actually reading the Bible supported my understanding that it was all fiction).
