Answer:
nonlinear
Explanation:
It has become increasingly popular in young adult novels to have
multiple narrators. Often, this is done through alternating
chapters. One chapter is told from one perspective, while the
next chapter is told from another. This can be done with either
first person or third person limited.
Multiple Narrators
This will likely mean that the plot is nonlinear in such a novel. The
reader will jump from one character and event to another (and
sometimes even see the same event twice, but from different
perspectives).
This is also sometimes called "alternating point of view".
