What is the narrator point of view in the novel, The Things We Cannot Say?

The author uses two first-person narrators. Alina narrates from the late 1930’s to present time as she tells the story of her great love for Tomasz. Her story is in past tense. Alina is a biased narrator because she is able to tell only what she knows about her situation. For instance, when Alina’s parents were still alive, she was not given much information about what was going on with the war. For that reason, Alina is unable to give many details about what happened during that time.
