"A Tree Grows in Brooklyn" is a 1943 semi-autobiographical novel written by Betty Smith. The story focuses on an impoverished but aspirational adolescent girl and her family living in Williamsburg, Brooklyn, NYC, during the first two decades of the 20th century.
Smith's book was a massive success and was produced in an Armed Services Edition so the novel could fit in a standard uniform pocket. The main metaphor of the book is the hardy Tree of Heaven, whose persistent ability to grow and flourish even in the inner city mirrors the protagonist's desire to better herself.
