All of Mary Stolz's novels are notable for their eloquence, maturity, and insight. [In a Mirror] is rich in these qualities. The diary form adopted for the story is ideal for Miss Stolz's purpose, which is to disclose the inmost thoughts of a college junior who seeks to understand herself and those about her. (pp. 68, 70)

Bessie's relationships—with Til, the instructor, her parents—are sensitively drawn and serve to enlighten her. Girls who read her story will be enlightened, too, as well as deeply moved. (p. 70)
