Genre
http://en.wikipedia.org/wiki/Genre
Genre is any category of literature or other forms of art or entertainment, e.g. music, whether written or spoken, audial or visual, based on some set of stylistic criteria. Genres are formed by conventions that change over time as new genres are invented and the use of old ones are discontinued.

Puberty is the process of physical changes through which a child's body matures into an adult body capable of sexual reproduction to enable fertilization. It is initiated by hormonal signals from the brain to the gonads: the ovaries in a girl, the testes in a boy.

Social novel
http://en.wikipedia.org/wiki/Social_problem_novel
The social novel, also known as the social problem (or social protest) novel, is a "work of fiction in which a prevailing social problem, such as gender, race, or class prejudice, is dramatized through its effect on the characters of a novel".
Metaphor
http://en.wikipedia.org/wiki/Metaphor
A metaphor is a figure of speech that identifies something as being the same as some unrelated thing for rhetorical effect, thus highlighting the similarities between the two. While a simile compares two items, a metaphor may compare or directly equate them, and so does not necessarily apply any distancing words of comparison, such as "like" or "as".
