She got all the way through Harry Potter with any real issues but she can be sensitive and about weird things. Being nine she is fairly narcissistic and it only worries her when bad things are happening the people characters she identifies with but we do like avoid over the top violence. She is fairly good at self censoring and will skip parts that make her uncomfortable, things like the basaltic and kissing.
The Inkheart books look interesting. I will have to find someone to recommend them to her. Dad is not allowed to have an opinion on clothes or books.
