Well it makes sense that 50 Shades of Grey is a nope for you if Twilight is. It originally started as twilight fan fiction and was apparently so popular that the author decided to self-publish. But since the names and characters were not her own, she had to change the names and a few characteristics or something? I love Twilight, but I hate fan fiction...it never captures the essence of the characters. So just based on that alone, I won't read it, but I'm also not into that genre at all, and I'm told by people who HAVE read it that the writing is terrible. So I'm staying away from that.
I loved The Help...I read it when it first came out. The book is way better than the movie, of course. I haven't read The Martian or Ready Player One though. I'm torn on Tolkein because while it's popular, my husband says he thinks it might be a bit too graphic for me. I get nightmares really easily from suspenseful books, so I trust his judgment on that. Also torn about A Prayer for Owen Meany...John Irving can go either way. I feel like his stories just ramble and don't really GO anywhere. I would like to read Alice's adventures in Wonderland and I actually have a copy of The Handmaid's Tale that I bought years ago from the bargain table at a bookstore and I just haven't had the guts to read it yet. The Giver is on my list, too, and Catch -22 and a couple others.
Have you read The Curious Incident of the Dog in the Night-time?
