A Tree Grows in Brooklyn wasn't a new book when my mother was young. It's the story of Francie Nolan struggling up in a tenement slum(贫民区)through the cracks in the pavement to reach the sun.It may be the best book I've ever read about poverty,parenthood, the immigrant experience,and just about everything else.My firstborn daughter is named

My all-time personal favorite. I love this book, all of it: the plot,the characters,the dialogue,much of which was lifted verbatim(逐字逐句地)by John Huston for his screenplay for the beloved movie of the same name.The single best monologue in fiction appears toward the end,when Sam Spade tells Brigid O'Shaughnessy why he's giving her to the police.

Oh-so hard to choose!But I'll go with Gilead.An uplifting tale of love in its many forms,told in a style in which every word is perfect.A joyous read.

If you think 700 pages on the many ways in which unusual kids(autistic, deaf, criminal, genius)can stretch(延伸)their families' conception(理解) of love doesn't sound like summertime reading,Far From the Tree:Parents,Children and the Search for Identity will teach you otherwise.
