It's simple. Incest is just not in line with the moral fabric of society and the positive values of the 'Harry Potter' series. The books are about things like friendship, loyalty, and good vs. evil, not inappropriate relationships.
The teen might learn about the importance of age - appropriate places. They will understand that there are places that are not meant for them at their age.
These novels often have strong moral lessons. In 'Percy Jackson & The Olympians', Percy has to learn about loyalty and friendship while facing numerous challenges. They can influence teens' worldviews by presenting different societies and cultures, such as the dystopian world in 'Divergent' which makes teens think about how a society should be organized. Moreover, the love stories in novels like 'Twilight' can give teens ideas about relationships, though not always in the most realistic way.
One popular teen adult novel is 'The Hunger Games' by Suzanne Collins. It's set in a dystopian world where teens are forced to fight to the death in an arena. Another is 'Harry Potter' series which follows the magical adventures of a young wizard and his friends as they grow up. Also, 'To All the Boys I've Loved Before' is a well - liked teen adult novel that deals with young love and family relationships.
One common story could be about a teen male who is mentored by an adult female. For example, in a school setting, an adult female teacher might see the potential in a teen male student who is struggling in a particular subject like math. She takes extra time to tutor him, and through their interactions, the teen male gains confidence not only in math but also in himself. This story can show how positive relationships between different age groups and genders can be beneficial.
The lack of access to contraceptives is a significant cause. In some areas, it may be difficult for adults and teens to get birth control pills, condoms or other contraceptive means easily. Poverty is also related. Some teens from poor families may see pregnancy as a way to get out of their current situation or may not have the resources to prevent pregnancy. Moreover, cultural factors can contribute. In some cultures, early sexual relationships are more accepted or there may be a stigma around discussing contraception, which can lead to higher rates of pregnancy.
One interesting teen adult story could be about a teen who volunteers at an animal shelter. They start off shy and unsure but through their experiences with the animals and the other volunteers, who are mostly adults, they grow in confidence and learn a great deal about responsibility. It shows how teens can interact positively with adults in a non - family setting.
