Rob Ryan gets animated

The publisher says this is the first time Ryan’s work has been animated – and it collaborated closely with him ‘to ensure that the tone and feel of the physical book was appropriately reflected in the finished product’.

The Invisible Kingdom tells the story of a young prince who uses an invisible-ink pen and a special torch to create a world that only he can see.

The ebook version features animated scenes from the book, as well as enhanced audio.

The Invisible Kingdom, by Rob Ryan, is available on Apple iBooks priced at £9.99.
