There are a couple of unclear age gaps in canon relationships. One character compliments another repeatedly in a way that is kind of icky, but it is seen as a joke in the canon. A lot of the book takes place in Klatch, a continent based on ancient Arabia, and contains some inbuilt stereotypes against Arab people. The relationship between a character and their father is heavily implied to be emotionally, verbally, and physically abusive, which is handled moderately well.
