i've recently read a book, which has made a very deep impression on me. it is named "gone with the wind" the author of the book is margaret mitchell. she was born in atlanta, georgia, in a family of the president of the atlanta historical society.  in 1939 the book was made into a highly successful film. vivien leigh won the oscar. everyone loved her high-spirited and beautiful heroine, scarlett  o'hara.

i too like this heroine. i advise to all to read this book!
