What is the author's style in Twisted by Laurie Halse Anderson?

Twisted is narrated by Tyler. He is a teenager starting his senior year of school. He has a dysfunctional family life and is not popular at school. He shares with us the story of what happens as well as his feelings, nightmares, dreams, and fantasies. This is the only point of view that the reader gets, so they are connected to Tyler. There might be other perspectives to consider, which would change our image of the situation, but we don't know any of them.

The reader is forced to bond with Tyler and accept his version of reality as truth. He has long struggled with suicidal thoughts and the reader thus has to navigate with him through all his emotions.
