'Merdeka' was shipped to Apple's iBookstore on 18th July 2012. All books are manually checked by Apple and can take up to two weeks from the shipping date to appear. It seems that the only way to see if a title is available is to search the iBookstore from an Apple device. Unfortunately my e-reading device is a Kindle and so I can't check :(
If any kind reader with an iPad or iPhone is able to search Apple's iBookstore for 'Merdeka', it would be hugely appreciated if you could advise when it appears. You can do this by leaving a comment below this post, or by sending me a direct message. Once I know that it is there and available I will update accordingly.
