They Cage the Animals at Night. To this day it’s the only non-fiction book I read, and even though it was for a school class, I really enjoyed it and glad I read it as I never would have taken it off a bookshelf otherwise. Very powerful and emotional story.
Western countries don’t have many, true. I honestly think that it’s because boy portal fantasies are more isekai/tower genre related from manga/manhwa from Japan and South Korea rather than how mainstream portal stories are done in the west. Most of these are videogame related or have elements of Murim and Wuxia themes, though there are a few more based on fantasy worlds (Tensei Slime and Overlord are two popular ones).
Like, out of all the isekai manga and manhwa I’ve read I can only think of less than a handful that are led by women MCs and not males off the top of my head.
Women led (just from my anilist that fit closest):
Male led:
And there are more, but I’m not going to list every single one.
I’ve never spent all my money on one series, but the first I got all the books for myself (not as gifts or through my parents when I was a kid) was Full Metal Alchemist. For more traditional books it would have been Spice & Wolf.
