If a story has a shifting point of view, then the fiction work will be more .

Inconsistent.

Explanation:

A shift in point of view occurs when there is a change in pronoun perspective such as changing from first person to third person pronoun, etc.

For example,

As WE drove into the city, YOU could hear the silence of the frightened residents.

There is an inconsistency in the sentence because of the pronoun shift which results in a shifting point of view.

That sentence can be rewritten with a consistent point of view such as:

As WE drove into the city, WE could hear the silence of the frightened residents.
