Although it is a little difficult to believe in the sustained cruelty of Roger's mother, [The Boy Who Could Make Himself Disappear] is a story so moving and so well written that one must accept her as a person whose aberrant behavior, deeply sadistic and selfish, has gone without notice because most of it is directed, in private, toward her only child…. [Roger's] sad musings on incidents of the past, his efforts to cope with his mother's hostility, and his valiant efforts to cooperate with the speech therapist are brilliantly told. (pp. 14-15)
