Just read it...
If there ever was any character I related to more than any other in literature, it would be Tatiana; I love that she is not the typical heroine: quite, reflective, a reader, melancholy, passionate without loosing her senses, etc. And that Evgeny is an anti-hero; I don't think American audiences see a lot of them, but then maybe I haven't read enough. ...As for the story, I enjoyed the pain and suffering that plays out between Tatiana and Evgeny, leaving them parted from one another.
(The opera and movie versions are both good too.)
