oh, sorry about that :(
Here's some information, about the 6? book of Harry Potter:
Is shorter than 'Order of the Phoenix' (less than 38 Chapters)
Titled 'Harry Potter and the Half-Blood Prince'
Three Chapters Titled Spinners End (Chapter 2), Draco's Detour (Chapter 6), Felix Felicis (Chapter 14)
To be released July 16, 2005 in certain parts of the world
The opening chapter had been tried for 'Philosopher's Stone', 'Prisoner of Azkaban', and 'Order of the Phoenix', but failed since it didn't fit correctly. The opening chapter for 'Half-Blood Prince' has been pending for 13 years.
'Chamber of Secrets' would have contained some 'Half-Blood Prince' connections, but J.K. Rowling cut it, seeing that it is too early in the series to unfold a major part of the story.
'Half-Blood Prince' was the working title for Harry Potter and the Chamber of Secrets; it was scrapped later on.
A new character by the name of Maclaggen will be introduced.
Cornelius Fudge has ran out of office; there will be a new Minister of Magic.
Details about the circumstances of Voldermort?s birth will be in book six.
More Rita Skeeter
According to Jim Dale (narrator of the Scholastic Harry Potter audio books), this book will have "more romance in general."
By reading Chamber of Secrets, you will not be able to find out what happens in Book Six, because Jo "...removed a whole storyline that did not work at all.... so I pulled it out and it became a major part, but not the only part, of book six." There is no trace of that story line left in Chamber of Secrets.
I hope that you like it ;)
