Every time I ask this question it seems like I get recommended stuff about characters that are not femboys so let me be very clear: I am talking about crossdressing boys that look like girls.
I am not talking about drag queens, otherwise masculine men with long hair, otherwise masculine men that have some “soft” character traits or hobbies, etc. I mean a cisgender male with a feminine gender expression.
Examples: “Prince and the Dressmaker” by Jen Wang, “Princess Jellyfish” by Akiko Higashimura, and “The Left Handed Booksellers of London” by Garth Nix.
