For my book I would say it is in the ecology branch, ecology is the study of other organisms in relation to how they act with each other and their physical surroundings. I thought that this definition and branch fit my book, the characters tackle everything interacting and intertwining in their lives. An example would be, how Finch pressures Violet into getting into a car after not riding in a car for so long because of how her sister dies. I also feel like there are no other branches that I can say that it fits, so it indeed fits the ecology
