A binary system in books refers to a type of story structure where there are two main characters or storylines that are interconnected and dependent on each other.
Some popular books with binary systems include "Harry Potter and the Deathly Hallows" by J.K. Rowling, "The Hunger Games" by Suzanne Collins, and "The Lord of the Rings" by J.R.R. Tolkien.
A binary system can enhance the reading experience by creating a sense of balance and contrast between the two main characters or storylines. It can also add complexity and depth to the plot.
One potential disadvantage of using a binary system in books is that if one of the storylines or characters is not as compelling, it can detract from the overall enjoyment of the book. It also requires skillful execution to ensure both storylines are equally engaging.
You can find more books with binary systems by searching for keywords such as "dual protagonists" or "parallel storylines" on book recommendation websites, or by asking for recommendations from friends or book clubs.
