What is the narrator point of view in the novel, The Girls: A Novel?

The novel is told from the point of view of Evie Boyd, both in the present day sections of the novel when Evie is middle aged and during the sections set in 1969 when Evie was 14 years old. It is made apparent throughout the sections set during 1969 that Evie is looking back on events a long time after they happened, although it is not made clear exactly how old she is when she makes these reflections and whether they are occurring concurrently with the story happening in the present day with Julian and Sasha. It is clear that Evie is narrating the events of 1969 in retrospect because she includes details from sources such as the police reports of the crimes, which she would not have had access to nearer the time.
