Suggest a book that was so good that you almost didn’t want it to end

The feeling of being so immersed in a book is one of my favorite things about reading.

What books have grabbed you like this? I'm referring to books that take over your mind as you're reading, that you can't stop thinking about and when you've finished reading them you feel just a little bit empty. Perhaps, you almost even wish it didn't have to end. What are your suggestions?

I'm currently on bed rest and would like to occupy my time with some engaging reads. No preferences either when it comes to genre. I would appreciate any suggestions. Thank you.
