What are some books that you thought had a perfect ending?

I've read some books lately where all the endings felt unsatisfying to me and it's putting me off reading. I like all sorts of endings and don't care if they get the fairytale, ride off into the sunset, die, time jump, epilogue - whatever - but I just want it to feel complete!

So, what are some books where you loved the ending and everything felt complete to you? I'm new to the sub, but if spoilers are allowed, please include them if you think it's necessary to say why you loved that ending.

TIA!
