You cannot start a new book yourself. You have to wait until the next book is put online by Rowling and so far it is not known when that will happen.
Once you have completed the first book, the second book will open for you to explore.
The only book left to be released on Pottermore is Harry Potter and the Deathly Hallows. A release date is currently unknown.
It's for the pottermore store and it is locked to all at the moment. It will open for ebooks and such in October.
New chapters are released when the developers are happy that they are completed. Announcements are often made on the Pottermore Insider a few weeks before new content is released.
As far as I know, we just have to wait until JK Rowling puts it on Pottermore, but I'm going to go crazy if she doesn't get it on there soon
you cant go to book two until its out of BETA testing in October
It is called Pottermore.
If you mean why can't you go into chapter 2 in Pottermore, this is because the book has not yet been opened. They want to leave the first book as the sole book for the time being to allow the new players to fully explore and experience both the book itself and the site in all, without having also the second book to experience. The way I see it, we should accept that these things are not yet open and simply wait to be given it.

If you mean book two, apparently early 2012
you dont get the second book until another load of people come online hope that helped :)
Yes, J.K. Rowling retained the rights to the Harry Pottere-books and began selling them. You can purchase the book, which is compatible with all e-readers, from the Pottermore store.
