The first chapter book I remember being read to me was "Stuart Little". My mother read it to me when I was sick with the measles, so I must have been around four. I remember being completely absorbed in the story and then asking for more and more chapter books.
My favorite books from my impressionable teenage years: " Gone With the Wind"; "Rebecca" and anything by F Scott Fitzgerald. More recently: "The Crimson Petal and the White"; "American Pastoral"; "Atonement"; " The Goldfinch" and "Life After Life." For pure escapism: The Jack Reacher series by Lee Child; The Alex Cooper series by Linda Fairstein and The Detective Lynley series by Elizabeth George.
I want to re-read Jane Austen. I was too young to appreciate her wit and irony when I first read her in high school. In terms of new fiction: "The Winter Soldier" by Daniel Mason and "The Huntress" by Kate Quinn (due in February ).
