News About Clockwork Princess Family Tree

As we all know, first edition Clockwork Princess books will all have the family tree.
Cassie tells us that the family tree will include the generation of The Infernal Devices, The Mortal Instruments, and The Dark Artifices!
The family tree will be printed either on the inside of the book jacket (hardback) or at the back (paperback). Make sure you don't spoiler it:

you will be sorry, because you will be mightily confused rather than illuminated. :)

But how do we know if it's a first edition?
Cassie shows us the North American version:

The cover will have "Collector's First Edition" printed underneath "Book Three" (beside the thumbs up)

This will be the same with the Australian, UK/Ireland, New Zealand, South Africa's first edition:

Sadly, there will be no family tree in the ebook because -as Cassie explains- there is no way to create a first edition ebook and it has a very nice design and the publisher would like to show it in the best way possible, by paper.

A first edition is the first batch of books that printed by the publisher and when they run out, there will be no more and  thus, the best way to guarantee a first edition is to pre-order at:

• Barnes & Noble
• Amazon
• Indigo Chapters
• Walmart (US only)

Also, Cassie does not know if the family tree will be present in other languages and the best way to find out would be by contacting a local bookstore.

Unlike Cassie's other books, there will be no other special content; nothing specified to  a specific store.
