One idea could be creating a "survival kit" based on The Walking Dead. You could include items such as a first aid kit, a water bottle with a filter, a flashlight, a portable phone charger, and any other survival items you can think of. You could package it in a cool container-like a backpack- and include a note that says "Surviving with you has been the greatest adventure" or something else sweet and meaningful. Additionally, you could also get her a special edition DVD set of the show or a collectible item related to the show, like a Funko Pop figure of her favorite character.
Or you can get her a star map with the date of your anniversary.
