The book is written in first person from Dolores Price's point of view. This point of view is at least slightly limited because the reader doesn't know what others are thinking and only knows of the actions of others when Dolores is present. The limit is not a huge problem for the reader because the story is meant to be truly from Dolores' point of view. The point of view is somewhat less limited by the fact that there are pieces of dialog and exposition that explain what happened whenever there are gaps.
The fact that the story is in first person means that the reader has the opportunity to look at the inner thoughts, dreams, and fears of Dolores herself. Though that may seem to be very helpful, Dolores is often confused.....
