How about getting your mom a copy of Angelica Ross's book "Pathway to Paris: A Manifesto for Our Planet"? This book is all about taking personal action to address the climate crisis, something your mom might be passionate about. Additionally, you could also consider getting her a t-shirt or hoodie from Angelica Ross's line, "Trans is Beautiful." Not only would it be a unique and meaningful gift for your mom, but it would also support a cause and a person that she loves.
Or you can get her a star map with an important date you share.
