Heretical Fishing

My daughter, age 12, saw Heretical Fishing on the Kindle Store and has asked to read it. I’m up to my ears in work right now and can’t take the time to read it myself. Is there anything “inappropriate” for a child of that age group? Thanks.

Edit: She just finished Hell’s Wardens in the Wandering Inn, the LitRPG series she has been reading for the past two years. When she comes across an “inappropriate chapter” she brings it to me and I either fast forward her through it or she reads it and we discuss it. The reason I ask is that she is going away with her grandparents for a week and they are not as chill as my husband and I.
