I'm about half way through War and Peace, and despite being extremely apprehensive about starting such a novel, I have been deeply surprised at just how much I have enjoyed reading it!
I had many people telling me I was too young (I am 14) and therefore not experienced enough to read War and Peace, and I must admit I found some of the novel hard-going but overall it has become one of my favourites.
I would recommend anyone to read it, however young or old.
