I thought the spanish version of book 6 was 'Harry Potter y el principe mestizo'. I could have sworn that's what my mate Andrea said. As for the differences between the English and Spanish I've only read book 1 in both languages and i don't remember findng any differences. It was a long while go though. something like 4 years. Anyway Ginevra, didn't you read book 6 in English? I have some friends who know alot less English than you and they read it. I was so surprised at their determination. It's like me trying to read it in French...Actually, maybe i will! At least i'll learn more even if it takes me months. I read book 6 in English in 2 days. Doubt that's the rcord though somehow.
