Гарри Поттер и философский камень

I found this book at the public library and I couldn't resist checking it out. I have never read the book in English.
After checking it out, I realized that I wouldn't be able to understand a word without a little help. Therefore I decided to check out the original text. Unfortunately, I couldn't find it; it was probably checked out. I did, however, find the French translation, Harry Potter à l'école des sorciers which works for me... I thought. Now I'm not so sure. Since these are both translations, it will be difficult to understand what the orginial text said. For example, the translated titles literally mean in English:
Гарри Поттер и философский камень - Harry Potter and the Philosopher's Stone
Harry Potter à l'école des sorciers - Harry Potter at the Sorcerer's School
