Esperanto doesn't have grammatical genders, though it does of course have words to represent gender since people want to distinguish between male & female. But if you don't want to, there are sufficient gender neutral pronouns (tiu, ri)

@cstross @gerikson Don't forget Enid Blyton, who also wrote large numbers of such (Malory Towers, St Clares, & the background to most of the other "adventure" book protagonists) who JKR undoubtedly read & whose career is quite comparable.
