I must admit I do love Hemingway's books. From what I have heard, Hemingway was not a nice person, but he did write well.
The Sun Also Rises was the first book of his that I read and while I wouldn't say it was romantic, it is so very well written and realistic.
Hemingway is one of the few authors that can write dialogue well.
A Moveable Feast is another one of my favourites, a brief snapshot of Hemingway's life, when he was happy.
So I am reading The Sun Also Rises, also known as Fiesta, again. It is a book I can read over and over again.
