Gone with the Wind by Margaret Mitchell. At the beginning, it was rather boring. Too much history, as for me. Of course, I don't mind history and I'm quite interested in it but sometimes I began to think about nothing, when reading. Later, I used to manner of writing and found the book not bad. Finally, I like it.
The Alchemist by Paulo Coelho. I was a bit afraid to read this book and suspicious of it. Now for me it seems to be very sunny and inspirational.
