I've loved Charlotte Perkins Gilman since the first time I read The Yellow Wallpaper, but this was actually the first work of hers I've read besides that. (My love was somewhat shallow.) 
 In light of The Yellow Wallpaper, and in particular Gilman's own time spent subjected to the "rest cure" favored by patriarchal, early-twentieth-century society (no surprise she left her doctor-husband who forced it on her, is it?), Herland is a pretty complicated book, examining gender roles and assumptions of what femininity is, through the eyes of three men. (The three men who found Herland are sort of a Goldilocks trio: this one is too brutish, this one is too sentimental/worshiping, and this one--the narrator--is Just Right, as he's the sociologist who sees the women as People, not Potential Conquests of Goddesses.) It does run to the preachy sometimes, with long passages of anthropological fascination with the women's culture, but overall, I really enjoyed this. I would have liked to see what happens once they leave Herland, but for that I need to track down the sequel.
