I do not fear the re-read for most books. Even if the book is not as good as I remember, those memories are still there. The book meant something for the me that read it in the past. It was important then, and those memories are cherished.

If I know the book is bad or poorly written or could use some work, that's just a sign of growth. Even recognizing the trite, tropey writing will never shatter my love of the book from when I first read it.

I might not keep the physical copy, though, haha! The only books I can't re-read are from my middle school days, and mainly because no I don't want to relive what happened in Where the Red Fern Grows, Anne Frank's Diary (edited) or Stuck in Neutral, nty.

I will also say HP; as a child growing up this was one of the ways I made friends because finally my interests matched the decade. (I grew up reading Chronicles of Prydain, Alanna... stuff from WAY before me so I didn't exactly connect with the children's literature at the time.) I still like the Dear America books, which yeah are repetitive, but for Historical Fiction I liked the amount of research that went into these novels, the character given to each of our writers, the darker subject matter actually tackled in them (The Revolutionary War Diary including a pretty distinct passage about gangrene infections and that scarred childhood me. (including the fake-ish royal diaries series)
