In 3rd, 4th, or 5th grade, my language arts teacher assigned our class to read a book called "Up _ Hill" (so, I'm guessing the book is targeted towards younger/preteen audiences). All I can really remember about the book's plot is that the main character is a young boy, and there's a nearby mysterious hill that he wants to climb. As for what I remember about the title, I am almost certain that the title was of the form "Up [name of the hill, which I don't remember] Hill". Whenever I try to think of the name, though, the only things that pop up are the words "Knox" and "Knockturn". Knockturn's likely from Harry Potter (Knockturn alley), so I don't think that's right. "Up Knox Hill" doesn't seem to return any relevant search results.
Summary:
- English book (novel) about a young boy climbing a nearby, mysterious hill. I read it around 8 years ago, in school (specifically, I think in 4th grade; definitely somewhere from 3rd to 5th grade).
- The title is of the form "Up [something] Hill", and I have a vague impression that the hill's name is similar to the word Knox.
- Book is likely targeted towards younger or preteen audiences.
- Book's appearance: handheld, the area was about average, but I do remember that it was a little thin.
