Tree Grows in Brooklyn, A by Betty Smith; 1943/1998. Softcover.

The Nolans lived in the Williamsburg slums of Brooklyn from 1902 until 1919 ... Their daughter Francie and their son Neely knew more than their fair share of the privations and sufferings that are the lot of a great city's poor. Primarily this is Francie's book. She is a superb feat of characterization, an imaginative, alert, resourceful child. And Francie's growing up and beginnings of wisdom are the substance of A Tree Grows in Brooklyn.
