Which book from your favorite author have you not read?

For me it’s The Shining by Stephen King. I just never happened across it, or if I did, I wasn’t interested at the time. But ever since Doctor Sleep came out, (the sequel to The Shining) they’ve been selling The Shining everywhere. So I decided to get it, supposed to be a classic King book. Reading it now.

What about you? What’s a book from one of your favorite authors that you haven’t read? Which book is it, and why did you pass it up?
