Halloween // What are your favorite bedtime/story time Halloween books for your little goblins?

What are your favorite bedtime/story time books? Do they teach important lessons. Is the artwork incredible? Is it one in a series?? I love reading but it’s been awhile since I was around children’s books. I’m looking to build a library for my son with ghosts, pumpkins, skeletons and monsters. I have a few classics but I’m looking for more classics and new favorites (and why).

Go ahead and assume I’ll (parent) be reading the book to my son for several years until he can do it himself.
