Part mystery, part psychological study, Happiness Falls explores the disappearance of a father through the eyes of his biracial Korean-American family. With a heavy focus on Angelman Syndrome and nonverbal communication, Angie Kim challenges our perceptions of intelligence and disability. Though dense with scientific footnotes, this 3-star novel is a profound inquiry into how we understand those who cannot speak, making it a must-read for psychology and special education enthusiasts.
