-Main character is a young girl.
-Girl goes to live with her aunts (might be good friends of parents and not relatives)
-Things seem normal except the girl is forbidden to read from a certain book the aunts have.
-One day the aunts get kidnapped and the girl must go into another world to find them.
-The girl has a companion that is a little dwarf, gnome, or other weird creature.
-As the girl progresses in her journey she learns new spells that help her progress.
-At one point the girl must get a new guide given to her by the bad guy (maybe) but she knows a spell that forces her old companion to tell the truth if the new guy is trustworthy so she gets a different one.
I know these details are really random but perhaps a random google search will get some stranger’s attention and they can help out. Or maybe one of you have just been holding out on me! 🙂
