A letter from a son to a mother who cannot read. Written when the speaker, Little Dog, is in his late twenties, the letter unearths a family's history that began before he was born -- a history whose epicenter is rooted in Vietnam -- and serves as a doorway into parts of his life his mother has never known, all of it leading to an unforgettable revelation. At once a witness to the fraught yet undeniable love between a single mother and her son, it is also a brutally honest exploration of race, class, and masculinity.
