What is the narrator point of view in the novel, History of Wolves?

The novel is presented in first person from the limited view of Linda, whose real name is Madeline. She is a teenaged student as the novel opens, but she writes from the vantage point of some two decades in the future, when she is a 37-year-old adult, still struggling to understand the events of that year in her life. She writes little of her current situation at age 37, meaning the novel is written in past tense.
