The Fangirl’s Guide to the Galaxy is a non-fiction book written by Sam Maggs. It is a great book for all geek girls and aspiring fangirls alike. If you’re new to the fandom world, it gives you great ideas where to start, and if you’re more familiar with it like myself, it can open up your fandom world even more. If you’re an expert? Well, it’s still a very entertaining read.
