Next assassin's creed book...?

i have been doing a little searching and i went on oliver bowden's page on fantasticfiction.co.uk and it says that there is a new assassin's creed book coming out called the secret crusade. however i checked this page a while ago and it said that the new book was to be called holy land. also if you go onto the page showing the entire assassin's creed series it says the book will be called holy land.

i also went on amazon and looked up both books and they both have pages with different isbn numbers but release dates within a few days of each other. however it does say that the secret crusade is currently unavailable.





http://www.amazon.co.uk/AssassinS-Creed-鈥?/a> - assassin's creed: the secret crusade





http://www.amazon.co.uk/Assassins-Creed-鈥?/a> - assassin's creed: holy land





can anyone explain what has happened and shed some light on the entire thing.





thanks|||Just checked Penguin books who published Oliver's books, australia have it listed and state it's being published by Penguin UK but there is nothing on the UK site.





If you click on the Australia link there is a short piece on the book...
