Books that the main character is dead.

I want a book that gives me Corpse Bride vibes or a book where the main character has died and is learning to “live” in the underworld/afterworld.

I’ve already read:
– If I Stay
– Lovely Bones

I know there has to be more books than those two, right?

Putting this as “Other” because it would be cool if it was a romance, but I’m really down for any genre as long as it’s not Children’s lol

TIA!
