I recomend you to read P.S. I Love You, because it is a very romantic book, but in a realistic way. It's very entretaining to read it, once you star it, you won't stop till the end of it.
I don't love to read, but this book was something i didn't expected.

It's about a very happy couple, that are merried, everything was perfect, till he found out he had cancer. From that day, things changed.

When he died, she thought nothing had sense. She didn't when out of her house for months, she was in a very huge depresion. One day, she went to her mother's house and found out, her husband wrote her a letter that said the month and something that she needed to do.
That was the best thing he could do, it helped her a lot. And the best part is that he left her one letter for each month, for a year.

I love romantic stories and this one is one of my favorites.
