Simon Shuker's Code-Cracker Volume Eight has now been printed and is being ordered by your local stockists. In addition, the out-of-print Volumes Three and Four have been reprinted, meaning that all eight books are available for purchase.

You should be able to buy the eighth volume from the same place you bought the other books: to help you here is the list of shops that have previously purchased copies. If the books aren't in your local store, they can order in copies - the distributor details are available here. Have fun!
