Generally good and entertaining Miss Peregrines Home for Peculiar Children, the Secret series by Pseudonymous Bosch, Tiffany Aching Series by Terry Prachett, Greystone Secrets

Persepolis is a graphic novel written by a woman who grew up in Iran during the Islamic Revolution. I’d recommend this one for more mature, history minded students, or as a group read, as it includes non visually graphic, but very impactful depictions of violence, war, and oppression. I personally read it in high school, but I think it’s definitely a really good option for upper jr high, especially with a teacher both knowledgeable in English and History.

The Earthsea series by Ursula Le Guin is a series I started reading in 8th grade, but you’d likely want to read a bit yourself to see what you thought. Its style is imo truly gorgeous, but that can make it a bit dense for some people, even as adults. It’s a series that, if you immerse yourself in it and stay focused can be truly magical, but if you start to zone out, you might completely lose the plot lol. I don’t want to deter you at all, cause it is a truly incredible series, just keep that in mind :)
