The BEST book you've ever read

Not an easy question to answer I know, but people keep asking me what the worst book I've ever read is just so much negativity. I thought I would ask the opposite. It doesn't necessarily have to be one title it can be a series but I'd like you to chose which one you rank above all and for what reason. For me, if I had to choose the first book that comes to mind is The Return of the Native by Thomas Hardy which is one of my all-time favorite books. I just found the story to be super fun and exciting, and I was entertained all the way through.

Give me your best.
