Many things have been said about Marcel Proust to myself as the sarrounding adults gushed over the fact that a teenager was reading literature. That said, many of these people confessed they had never finished Proust all the way through; one went all the way to say he had found it too "subjective." If you are reading literature to read literture STAY AWAY FROM THIS BOOK! If you want to read an incredible novel, then go ahead; you will not desecrate Proust's grave.
Many times as I read this book, I found myself pausing, almost pained at the beauty of the language. I have read many authors, and have never read such beautiful words; his descriptions seem so divine, and yet he spends the first part of the book saying that he himself can't write! It's one of those moments where you want to shake the author with mental fists, but it's okay; it adds flavour.
Proust is probably among the greatest novelists of history (probably one down after Dostoevsky). The title of the series "In Search of Lost Time," immediately gives you the clue of what the theme shall be; moments of wasted time, moments of bliss that you wish to recapture, memories long gone that you wish you could recapture. But, that is the essense of life.
