[In the following review, Reiher briefly describes the obstacles that Birdie, the adolescent narrator of Senna's Caucasia, faces as she grows up.]

The time is the 1970s, the place is Boston, and the story[, Caucasia,] is of a biracial marriage and the two little girls born of it. Cole, the first child, preferred by both parents, is beautifully black like her father. Birdie, the narrator, is light enough to pass as white. The wife is a "bleeding heart liberal" who has involved herself in civil rights causes against the wishes of her intellectual husband. Finally, the marriage ruptures. A general breakdown ensues when a gun-running political activity precipitates the need for the family to disappear. Cole is taken off to Brazil with her father to begin a new life in a black environment more open to people of color. Birdie is caught up in a series of wrenching deprivals when her mother insists on the need to go underground. There is a change of location, name, appearance, and in Birdie's case, a change of race; she is to pass as white. Money shortages, a complete lack of stability, the loss of a sister almost a twin, a feeling of displacement, the strains of adjustment, no sense of community or relationship, and the growing suspicion that her mother is psychotic make for disturbing adolescent years. Throughout, Birdie keeps alive her need to connect with her father and sister, and faces the knowledge that the liability of her sister's blackness to her mother and her own unwelcome whiteness to her father has brought the family to this sorry situation. It is her courage, her optimism, and her inherent loyalty that brings about a satisfying reunion for the sisters.
