It may be a bit too... easy, but I still would like to give a shout out to Brandon Mull's series Fablehaven if she is into fantasy. Great series that's a bit on the lesser known side in my experience.

Also, especially if she has any interest in mythology, The Secrets of the Immortal Nicholas Flamel is really good too.

The cover and the fantasy world aspect sound like Fablehaven.

Fablehaven! (by Brandon Mull). Loved it as an adult, totally kid-friendly.

Honestly shocked it hasn't been recommended yet.
