PotterMore to launch final COS chapters for Halloween!

Just in time to celebrate Halloween,
PotterMore has announced their intention
to launch the final interactive chapters of
Harry Potter and the Chamber of Secrets
within the next day or two.

Here is the official announcement, issued through the PotterMore Insider:
"You may have seen the spiders here on the Insider and on our Facebook and Twitter
pages recently. Yes, we’re talking about our many-legged visitors and if you’ve
noticed them, then you may have remembered Hagrid’s advice ‘ter follow the spiders’...

Now, it’s your turn to find out some stuff as we can announce that the final and last
installment of Harry Potter and the Chamber of Secrets will be released sometime
this coming week.

Chapters Twelve to Eighteen will shortly be available
for you to delve into and explore.

Brewing Polyjuice Potion, accessing the Slytherin common room
and uncovering the secret of Tom Riddle’s diary are amongst
the many exciting Moments awaiting you.

These concluding chapters will also contain brand new exclusive content from J.K. Rowling, including material on the Chamber of Secrets; its origin and history."
I expect we can look forward to unlocking more hidden material,
which usually is well worth the effort in seeking it out.
But for now, we will have to follow PotterMore and "follow the spiders".
