Chronicles of Narnia

So I watched 'Chronicles of Narnia - The Lion, The Witch, and The Wardrobe' tonight.... I read this book in 5th grade (a super long time ago) but I didn't remember any of it at all. The only thing I remember was my class project where I made a scene from the book carved out of Ivory soap (yeah I was cool, and smelled like Ivory for a week!) After watching the movie, I am shocked they let us read this book at such a young age. There was a lot more fighting than I remember (oh wait, I didn't remember any of it) I thought the movie was great, but this book could be traumatizing for little kids (I mean, in 5th grade I was what, 11) And also, I know this is the 3rd out of a series of 7, and I haven't read any of the other ones, but I really can't figure out what else this series could hold. There was a real beginning and ending to this book, no cliff-hangers, no needing to know information before to know what's going on. What else could be held within these other 6 books... are the kids a part of them, or is it another set of kids? Is there more than one war, or does peace stay in Narnia? I just can't fathom what the other books hold.... I guess I know what I'm reading this summer, besides the HP books again ;)
