New Adult
A genre of fiction with protagonists in the 18-30 age range.
NA tends to focus on themes such as: leaving home, developing sexuality, choosing careers, beginning college, starting families, financial independence, loss of innocence, fear of failure, and friendships post-high school.
It is typically considered a mixture of the YA and ADULT genres.
YA themes I tend to incorporate: family life, friendship, relationships, sexual interest, identity, working through problems, and learning to be responsible.
ADULT themes I tend to incorporate: the emotional development of a relationship, graphic sex scenes, multiple sex scenes, graphic violence, existential musings, and family dynamics.
