Purchased the 11-book 39 Clues series in paperback and it does not come with 6 cards for each book.
On the cover it says we can add cards by being asked two questions about each book and it will unlock the six cards for that book.
I do not see this option and am unable to unlock cards since we do not have a code with each book.
Any thoughts or help would be greatly appreciated.
