How about gifting her a “how-to” book on comic book writing? There are some great options out there such as "Understanding Comics: The Invisible Art" by Scott McCloud or "Drawing Words and Writing Pictures" by Jessica Abel and Matt Madden. You could also get her a sketchbook or a set of high-quality pens, so she can start writing and drawing her own comic book. And if you really want to go all out, consider gifting her a subscription to a comic book writing class or workshop to help develop her skills even further.
Or you can get her a star map with an important date you share.
