What is the narrator point of view in the novel, Zero Days?

This novel is told from the first-person point of view of Jack. Consider the sentence: “It was nearly four a.m. before I got back home to Salisbury Lane, and I was half-drunk with exhaustion, my eyes scratching with tiredness as I wove mechanically through the near-deserted residential streets of South London” (33). Jack refers to herself with the pronouns “I” and “my” (33). She describes her own thoughts and emotions, but she is limited to what she knows or finds out from other characters.
