Sci-Fi I've loved lately, which feature diverse casts and tackles identity and social dynamics in interesting ways:
Wayfarers series by Becky Chambers, starting with "Long Way to a Small, Angry Planet".
Martha Wells' Murderbot series, satrting with "All Systems Red".
The CatNet series by Naomi Kritzer, starts with "Catfishing on CatNet". this is the only one explicitly targeting tweens, but also content warning about parental abuse.
I’ll look into CatNet. Also thinking about maybe Scalzi, since I consider that lower reading level. I don’t know about content appropriateness, though. Either in terms of interest or, like, sex scenes or whatever.
@benhamill @guerrillarain If I might suggest, Anne McCaffrey's Chronicles of Pern would be a great crossover from fantasy into sci-fi. On similar theme, Terry Pratchett's Truckers series is probably a good starter for younger reader. One of my all-time favourites is James Schmitz Witches of Karres - space opera sitcom. If reading more advanced, try Larry Niven's Ringworld.
@benhamill To jump in not directly bidden: Dragon Pearl by Yoon-Ha Lee comes to mind as one I read recently that was definitely on the Y side of YA, it's protag is a 13yo. Probably depends on the kiddo, there's some light scary stuff involving siblings that are now ghosts, and some background military stuff, as scifi is wont to have.
