There is an absolutely fantastic series called The Gilded Ones by Namina Forna that she would probably love; I saw it on a list of books that are a way better alternative to Harry Potter, read it, and haven’t stopped recommending it to others.

The Wayfarers series by Becky Chambers is a great warm-and-cozy kind of sci-fi, also well worth the read.

The House In The Cerulean Sea by T. J. Klune is a beautiful read about a group home of misfit children

The Deep by Rivers Solomon, an interesting twist on a mermaid story

The Psychology of Time Travel by Kate Mascarenhas is a really cool story that mixes up a murder mystery with time traveling

The Maise Dobbs series by Jacqueline Winspear; the series starts in the 1910s and follows a young girl who grows up to become a private investigator in the 20s and 30s

Almost anything by Neil Gaiman, but particularly The Graveyard and Coraline are awesome, creepy reads, if she’s looking for something like that
