If your goal is to make money, it's essential that you are
aware of market trends and audience expectations. For example, you need to know that successful YA books are often written in first person and romance books in third person limited, while second person is quite rare and may be seen as experimental. However, you don't have to let the market
dictate your POV. After all, bringing a refreshing new spin to a genre can get your book noticed. Rather, it's about knowing the effect of each POV and figuring out what's best for your story
and your readers, so that any decision to go against market trends is a deliberate, justified one.
What effect does each POV have? In short:
- First person creates intimacy and subjectivity.
- Second person immerses the reader fully in the story (when done well).
- Third person limited offers a less biased but still intimate experience.
- Third person omniscient shows multiple perspectives / plot lines.
