My 9 year old can't get enough of percy jackson. There are three 5 book series that she's read now. It's gotten her really into Greek mythology and she loves seeing Greek mythology everywhere. Like Achilles heels, the NASA space ship named Artemis, etc.

My 9 year old is working her way through the original Nancy Drew series. She frequently has to stop and ask me questions about what certain outdated phrases mean or what things are, I love it!

My girls are now grown, so I can’t attest to popularity, but here are some books our family has enjoyed:

My 9 year old would cosign all of these but Babysitter's Club (she just hasn't read them). She would also add Tuesdays at the Castle and Princess Academy (more for 9 than 8 on the last one I think).

Little House series
Zoey and Sassafras series
The Pug Who Wanted To Be series

My DD loved Junie B Jones and her more modern counterpart, Dory Fantasmagory.

We read Harry Potter together that year too, with me doing about 90% of the reading because it was above her reading level.

World According to Humphrey has been a hit here for an animal lover

Mine likes Boxcar Children series (the originals), Heartwood Hotel series, Little House series, the Penderwicks, Roland Dahl books, Babysitters Club (not the graphic novels).

Warriors - the graphic novels are good for this age.

Also the rainbow fairy books and babysitter club.

Katie the Catsitter graphic novels, Wings of Fire

My DD and her friends are really into graphic novels for Babysitters Club and Sweet Valley. They also like anything by Rania Telgemeier.

Other popular series are the Whatever After books, the Ramona books, and anything by Grace Lin.

I think it was in third grade that the Warrior books were really popular for my kids. Both boys and girls seemed to like them a lot.

I don't know if it's popular with this age group, but my 8 year old loves the Wollstonecraft Detective Agency books.

Dork Diaries. Super trashy but third grade DD and friends love them.

DD has also recently read and enjoyed Charlotte’s Web and Little House in the Big Woods, if you want something more classic for that age group.

What books are popular with 8-9 year old girls?
