Herland is a turn of the century feminist utopian novel about three rich American dudes who seek out to discover (i.e. subdue and conquer) an isolated nation where there are no men. It's easy to make comparisons to Themyscira - girls are trained to enable them to protect themselves from a non-existent threat, educated to improve their society as well as themselves, and nurtured in a sisterhood whose religion is based on the honor of collective motherhood and ensuring the success of future generations.
Enter the menfolk: Jeff, a drippy romantic who yearns for a woman to protect and idealise, the kind who'd probably burst into tears if the lady of his affection let rip a stank pizza-and-beer fart; Terry, an oily lothario convinced against all evidence that he can vanquish the hotties for his own personal harem; Van, the level-headed sociologist narrator increasingly filled with doubt and guilt as he is educated in the ways of Herland (their term).
The penny drops for Jeff and Van - "We were now well used to seeing women not as females, but as people; people of all sorts, doing every kind of work", but gross Terry playacts his education and manages to ruin it for everyone. What a tool.
Being "of its time", Herland is chock full of gender essentialism and tiresome references to savages (naturally the ladies of Herland are all white). Everything else is very sign me up - big up the vegetarian diet and garments of many pockets! I enjoyed this short book, though it did feel like it ended somewhat abruptly where a "ten years later" style epilogue could have answered some unfinished questions.
