Bests & Worsts Reviews from Amazon

I bought these to replace my books I have had forever and got destroyed. Well I hadn't gotten a chance to read them until recently when I decided to reread them. I read the first (socerers stone) and second(chamber of secrets). I went to read the third, the prisoner of azkaban instead it was a chamber of secrets eith a prisoner of azkaban jacket overtop. So I go to look and my "goblet of fire" is actually another "order of phoenix". So instead of having books 1,2,3,4,5,6,7 I have 1,2,25,5,6,7. I am so angry right now! I wish I had looked earlier and discovered I had been screwed.
