This is a great question because I love reding very much.
This year I've read lots of books, so it's a bit difficoult answer the question. But I think the best book is Jane Eyre by Charlotte Bronte. I love everything of this book: romance, her way to be, all the descriptions and, of course, the handsome character of Edward Rochester.
But other books deserve a little mention. In fact this year I've discouvered Jane Austen and I've totally loved her books - in order of preference, Pride and Prejudice, Persuasion, Northanger Abbey and Emma. I've also read some beautiful books by Joanne Harris, like Chocolat, The Lollipop Shoes, The Evil Seed and Runemarks (reading by now). I can't close this post if I don't tell you of J.R.R. Tolkien, Glenn Cooper and other brilliant writers who have accompanied my years with awesome books. You can find all my readings here.
