Here are a few nice ways to help a writer:
-buy their book
-review their book
-draw fan art based on their book
-construct a diorama based off a scene in their book
-juggle copies of their book at a haunted circus
-feed their book to a cosmic bookworm with a billion teeth
-read their book aloud to a basement of faceless mannequins
-gift them a cursed pen that periodically grows tentacles
-bribe a trio of sirens to sing about the book to passing sailors
