The Hobit and the Chronicles of Narnia sparked my love of literature when my mum read them to me before I could even read, and again when I read them myself a few years later.
Harry Potter - I was eight when I started reading them (this was before they were famous, when only two were out), and subsequently I grew up with Harry. I'll admit proudly that I was part of the Harry Potter generation; The kids who grew up discussing what was going to happen in the next book for all the year/s in between their releases. We would dissect every rumor that appeared a thousand times over. It was us lining up outside the book stores for every new release.
That anticipation was almost better than the books, and I don't know of anything else in other period or thread of my life that has given me such endless happiness and excitement. In that, Harry Potter had a profound effect on my life.
Of Mice and Men - the first time I was introduced to what is now a central belief in my life, that the dream itself is more important than its attainment.
The Wife of Martin Guerre - Although short, this is one of the most important novels I have read, for it was reading this that I understood something that has changed the way I read ever since. You don't have to enjoy a book the first time you read it for it to be a great novel. Quite frankly I thought I had never read anything so boring the first time we read it back in lit when I was still in school. The second time we read it I started to find it interesting, though still not that enjoyable. I read it a third time out of class before writing an essay on it, this time i genuinely enjoyed it. Since then I have read it more times than any other book, and I swear I enjoy it more every time. It is now one of my (i have no singular) favourite books, which is a long way from being bored as I was when i first read it.
The Illiad- Most people group both the Illiad and the Odyssey together, but I don't like too. I think the Odyssey was a more enjoyable work to read, though it is in my opinion, incomparable to the power of the Illiad. The first time I read the Illiad i thought I had a grasp on its power and greatness, that was, right up until i read the final line. At that moment, i realised that until then I hadn't even begun to comprehend this work. It left me catatonic, after that final line for about half an hour I couldn't move, I just sat, transfixed by the raw emotion that tore through me. It really is an indescribable greatness that the work contains, the best way I can to describe it is to say; Before I read the Illiad i was sure at least part of it fame came from being famous, that at least in part it was still read because it is the oldest work in western literature. What can I say? I was completely wrong, it's fame comes because it truly is one of the greatest works of literature. It is still being read after 2700yrs, and still exists after 2700yrs, not because of its age but because it is one of the greatest works of all literature.
lol, i seem to have got caught up in the moment :-p
