The second-person narrative is a narrative mode in which the protagonist or another main character is referred to by employment of second-person personal pronouns and other kinds of addressing forms, for example the English second-person pronoun "you".
I say, it was super-annoying. Every time I read "you" it took me out of the story. I kept thinking, "Who you? Me? But I'm not a futuristic detective investigating a kinky murder and missing my hair-do appointment. Why did this author use second person?" Suffice to say, I couldn't stick it out and didn't finish the book.
Caveat Scriptor! As a writer, you should think carefully before you try using second person. Is it really what your story needs? If so, go for it! :)
Of course, there have been successful fictions written in second person. Oh, the Places You'll Go! by Dr. Seuss (1990) comes to mind.
I must admit, I do like second person for blog entries. :)
How about you? Have you read or written any good second person?
